Question

2. A 2.5 mol SAMPLE OF OXYGEN GAS (O2) INCREASES TO 3.2 mol

Answer 1

696.32 mmHg is the final pressure of the gas.

What is an ideal gas equation?

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.

Given data:

$P_1$ = 720 mmHg              

$P_2$ = ?

$n_1$ = 2.5 mol                

$n_2$ = 3.2 mol

$V_1$ = 34 L            

$V_2$ = 45 L

Formula

Combined gas law

$\frac{P_1 V_1}{n_1} = \frac{P_2 V_2}{n_2}$

$P_2$ = 696.32 mmHg

Hence, 696.32 mmHg is the final pressure of the gas.
