What is the pressure inside a 10.0 L flask containing 14.2 g of N2 at 26 degree celsius. Please show your steps. Iwant to see if I set my problem up correctly. Thank you?

Use this formula. PV = nRT. Need to convert grams N2 to moles N2 and temperature Celsius to temperature Kelvin( add 273.15 )
14.2 grams N2 ( 1mole N2/28.02 grams) = 0.507 moles N2
26 degrees C = 299.15 Kelvin
(pressure)(10.0 liter) = (0.507 moles N2)(0.08206 Latm/molK)(299.15 K)
= 1.24 atmospheres pressure
Thank you so much for your answer. I did end up figuring it out on my own.

A 500 ml oxygen sample is collected over water at 4 degree celsius the total 750 mmHg.What will be the pressure of oxygen gas if it is dried.What volume will the dry gas occupied at STP?
to figure out the pressure of the dry gas, use this equation: Pgas= Ptotal - Pwatervapor ...(P means pressure) you need to find a conversion chart of 4 degrees celsius (into mm Hg/torr/atm) : http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Vapor-Pressure-Data.html 4 degrees celsius = 0.81359 kPa ... convert to mm Hg by dividing by 101.325, then multiply by 760.0. 4 degrees celsius = 6.10mm Hg now plug into the problem above... Pgas= 750mm Hg - 6.10mm Hg = 743.9 mm Hg of dry oxygen gas ...that should be the correct answer, check with a chem teacher or something. ...I myself am trying to figure out how to solve the volume of dry gas at STP later to figure out the pressure of the dry gas, use this equation: Pgas= Ptotal - Pwatervapor ...(P means pressure) you need to find a conversion chart of 4 degrees celsius (into mm Hg/torr/atm) : http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Vapor-Pressure-Data.html 4 degrees celsius = 0.81359 kPa ... convert to mm Hg by dividing by 101.325, then multiply by 760.0. 4 degrees celsius = 6.10mm Hg now plug into the problem above...

If there is a problem with the muscles of the pupil then it will not regulate light into the eye correctly.
A piece of iron absorbs an amount of heat when it is heated from 22 degrees Celsius to 28 degrees Celsius- How many joules does it absorb?
There is not enough information in this problem to answer the question. You must know the mass of the iron to find the amount of joules used to heat the iron.
A gas is placed in a storage tank at a pressure of 20 ATM at 20.3 C there is a small metal plug in the tank made of a metal alloy that melts at 125C what is the maximum pressure in the tank?
The safety valve will melt when the gas pressure is approximately 40.7 ATM.That is false. The safety valve will not melt when the gas pressure is approximately 40.7 mL.The correct procedure for solving this problem is as follows:Considering the ideal gas formula: PV = nRT,Pressure and temperature have a direct relationship.In other words, P = TThe formula, derived from the ideal gas formula to solve this problem is therefore:P1 P2___ = ____T1 T2P1 = 20.0 ATMT1 = 20.3 degrees Celsius + 273.15 = 293.45 KP2 = ?T2 = 125 degrees Celsius + 273.15 = 398.15 KP2 = ((20.0 ATM) (398.15 K))/(293.45 K)P2= 27.13579826 ATMP2 ~ 27.1 ATM (rounded using significant figures)As can be seen, the pressure at which the metal alloy metals is 27.1 ATM.
How many moles of gas are present in a 10L container when 3.84atm of pressure is exerted at 35 Celsius?
Assuming that gas being used is an ideal gas, the gas law equation PV=nRT can be used. P=Pressure (atm) V=Volume (Liters) n=Moles R=0.08206 (a gas constant) T=Temperature (Kelvin) In this problem we know that there is a 10L container with 3.84atm of pressure at 35 C. So P=3.84atm, V=10L, and R=0.08206. To calculate T, you need to convert from Celsius (C) to Kelvin (K). Using the formula K=273+C, you should get T=308K. Now you know all of the variables you can work the problem out. Solve the equation for moles(n) by dividing each side by R and T: (PV/RT)=n Plug in your numbers and solve with a calculator: n=(3.84)(10)/(0.08206)(308) =(38.4)/(25.27448) =1.5193190918 Leaving us a rounded answer of 1.52n in the container
Can budgies live in -10 to 50 degrees celsius just a random question lol?
Not much can live at 50C. Budgies and -10C - no problem if housed correctly.
When the tire pressure light goes on in a mini cooper should you check the tire pressure?
Yes. The light means that one of the tires is not reading correctly. Either from improper pressure or a sensor problem.
The normal boiling point of cyclohexane is 81.0 degrees Celsius what is the vapor pressure of cyclohexane at 81.0 degrees Celsius?
The vapor pressure of anything at its boiling point is 1 atmosphere. That is the definition of boiling point, the vapor pressure is just enough to overcome atmospheric pressure. It could also be stated as: 760 mmHg (torr), 29.92 inHg, 14.696 PSI, 1013.25 millibars, or 0 PSIG.ImprovedThe problem to answer this Q. correctly, is that the atmosferic pressure is NOT the same as one atmosphere: On sea level and under normal, average weather conditions it is most of the time true, so then the A. is correct.But high in the mountains cyclohexane will boil at a lower temperature (than 810C) because of the lower (than 1 ATM.) atmosferic pressure.The above definition of boiling point is CORRECT, but the first statement (The vapor pressure of anything at its boiling point is 1 atmosphere) is NOT

The temperature on a winter night in Peekskill is -6o Celsius The temperature decreases by 8o Celsius What is the new temperature in degrees Celsius?
This is a mathematical word problem. Since we're using the modifier "decreases" we understand our problem will be substraction.-60C - 80C = -140C.
What temperature is 15 degrees lower than seven degrees Celsius?
Eight degrees below zero Celsius. It is a subtraction problem.
How do you convert degrees Celsius per mm Hg to just degrees Celsius?
You can't. Celsius per mmHg is a relationship of temperature to pressure. You can however solve for temperature if you have the value of pressure (e.g. if P= 10 mmHg and V/P = 2 ºC/mmHgthen V= (2 ºC/mmHg)(10 mmHg) = 20 ºC). If you have more information in the problem you might be referring to Gay-Lussac's Law, which compares two values of pressure and temperature to show the relationship (GL'sL: P1/T1 = P2/T2 ... but that would be pressure per unit volume). I'm not sure what you are looking for exactly, but you can't convert temp. to pressure (just like you can't convert feet to lbs.).
