# How do you solve gas laws problems with the given "at STP" and with mass?

I like to use the Ideal Gas Law.

The Ideal Gas Law is:

where

We can rearrange the Ideal Gas Law to get

Also,

EXAMPLE

What is the volume of 10.0 g of hydrogen at STP?

Solution

Remember that STP is defined as 0 °C and 1 bar.

To solve gas law problems with the given "at STP" and with mass, you can use the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. At STP, pressure (P) is 1 atm and temperature (T) is 273.15 K. To find the number of moles (n), divide the given mass of the gas by its molar mass. Then, substitute the values into the ideal gas law equation and solve for the unknown variable.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What are the mole fractions of each component in a mixture of 15.08 g of #O_2#, 8.17 g of #N_2#, and 2.64 g of #H_2#? What is the partial pressure in atm of each component of this mix ture if it is held in a 15.50-L vessel at 15°C?
- A sample of argon gas occupies a volume of 950 mL at 25.0°C. What volume will the gas occupy at 50.0°C if the pressure remains constant?
- A flask contains oxygen, carbon dioxide, and nitrogen gases. The partial pressures of each are 11.4 atm, 5.6 atm, and 8.7 atm respectively. What is the total pressure in the flask in atm?
- What is the pressure inside a tank that has a volume of #1.20 * 10^3# L and contains 12.0 kg of #HCl# gas at a temperature of 18°C?
- A steel cylinder contains N2, O2 and CO2 gases the total pressure in a tank is 3.00 ATM the partial pressure of the N2 and O2 are 950 torr in 1025 torr respectively what is the partial pressure of CO2 in atm within the mixture?
