Given pv equals kt solve for k?
k = pv/t. It is not possible to solve further with the information available.
Can air preesure go down to negative numbers?
Yes, because PV=nRt From this equation it becomes apparent that air pressure, V, can be negative. Since negative temperatures can exist, such as -30C (remember you have to use Celsius and not Fahrenheit). Thus we have negative numbers for air pressure.
How do you calculate PV ratio?
PV ratio= contribution/sales*100
How many air molecules are in a 13 x 12 x 10ft room Assume atmospheric pressure of 1 00 ATM a room temperature?
To solve this problem, several different steps must be taken. Convert Volume = 13*12*10 = 1560ft^3 * 28.2 = 43992L ~28.2 Litres per cubic ft Ideal Gas Equation: PV=nRT Rearrange: n=PV/RT Temperature:273+20=293K n=[(1*43992)/(0.0821*293) = 1828.78 1 mol Air Molecules = 6.022*10^23 Air Molecules 1828.78*(6.022*10^23) = 1.10 * 10^27
What is the real mass for 1 liter of air?
The following calculation is based on the following assumptions: 1. The composition of air is 78% Nitrogen, 20.95% O2 and 0.93% Ar. 2. Air is an ideal gas: i.e. Obeys the equaiton PV = nRT. The mass of 1 L of air at a pressure of 1 atmosphere and at 25oC is 1.18 g.
Pv equals rnt solve for v?
V=nRT/P
Solve each formaul for the indicated variable pv - nrt for v?
p v = n r t v = n r t / p
What does the R stand for in PV equals nRT?
r is the constant 0.0821
What tells how gases should ideally behave?
PV =nRT
What forms of the ideal gas law would you use to calculate the number of moles of gas?
This is the general law of gases:PV = nRT (n is the number of moles)
What form of the ideal law would you use to calculate the number of moles of a gas?
From PV = nRT you solve for n (moles). Thus, n = PV/RT
What of the ideal gas law would you use to calculate the number of moles of a gas?
From PV = nRT you solve for n (moles). Thus, n = PV/RT
How do you find the temperature if pressure is kept constant?
PV=nRt. If P is constant, get the value of V and solve for t.
Solve using the rule of 72 rate equals 4 percent years equals 18 fv equals 8000 solve for pv?
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
