IDEAL GAS LAW AND PARTIAL PRESSURES

=================================

To solve this problem, we need to know the ideal gas law equation:

PV = nRT

Let's plug in the numbers of what we know.

V = 75.0 L
T = 22 C = (22 + 273) = 295 K
R = 0.08206 L-atm/mol-K

What else? We need to know n (moles) in order to calculate P (pressure).

We need to determine the total number of moles of gas.
We have 9.00 g ...

#### Solution Summary

This solution discusses pressure exerted on a gas mixture.
