That's going to depend on the substance,
which the question neglects to identify.

The volume of any gas at STP (pressure of 1 ATM & temp.: 0oC) is approximately 22.41 L/mol or 22,410 mL/mol. So you need to find out how much gas you have to begin with (# of moles) to find the volume of the gas at STP.
30 degrees Celsius = 303,15 K752 mmHg = 0,9894737 atmosphere
The vapor pressure of water at 65 degrees Celsius is approximately 170.4 mmHg.
The vapor pressure of CH3OOH (methoxy) at 20 degrees Celsius is approximately 19.26 mmHg.
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...

To find the volume of neon in the new conditions, we can use the combined gas law. Given initial conditions (T1 =127°C, P1 = 450 mmHg) and final conditions (T2=227°C, P2=900 mmHg), we can calculate the final volume V2 using the formula: (P1 * V1 * T2) / (T1 * P2). Plug in the values to get the final volume of neon.
A fixed quantity of gas at a constant pressure exhibits a temperature of 27 degrees Celsius and occupies a volume of 10.0 L. Use Charles's law to calculate: the temperature of the gas in degrees Celsius in atmospheres if the volume is increased to 16.0 L
30 degrees Celsius = 303,15 K752 mmHg = 0,9894737 atmosphere
47 degrees Celsius
The vapor pressure of water at 65 degrees Celsius is approximately 170.4 mmHg.
The vapor pressure of CH3OOH (methoxy) at 20 degrees Celsius is approximately 19.26 mmHg.
Oh honey, you're mixing up your units like a bad blind date. Celsius measures temperature, while mmHg measures pressure. It's like comparing apples to oranges, they just don't play in the same sandbox. So, to convert Celsius to mmHg, you might as well be asking me to turn water into wine - it ain't gonna happen.
The volume is 0,446 L.
757.2 mmHg is almost atmospheric pressure (P = 760 mmHg) and therefore the vapour pressure is very close to the normal boiling point.According to the boiling temperature is T = 353.14 K = 79.99 °C at P = 757.2 mmHg.
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.).
Yes it does. And STP also stands for 760 torr and 1.0 ATM and 273 K.
PV=nRT (pressure*volume=mols*value for R*temperature in degrees kelvin) R Values vary, but must match the unit for pressure---> .0821 ATM 62.4 mmHg 8.314kPa temperature must always be in degrees kelvin ( kelvin= degrees celsius+273)
The vapor pressure of propanone (acetone) at 45 degrees Celsius is approximately 365 mmHg according to reference table h.
