**Problem**: What is the pressure in a 7.50 L flask if 0.15 mol of carbon dioxide (CO 2; molar mass = 44.0 g mol–1 ) is added to 0.33 mol of oxygen (O 2; molar mass = 32.0 g mol –1 )? The temperature of the mixture is 48.0 °C. A. 0.252 atm B. 0.592 atm C. 1.69 atm D. 3.97 atm E. 4.80 atm

###### FREE Expert Solution

We are asked to calculate the** pressure of the gas mixture. **

We will use **ideal gas equation** to calculate for the pressure:

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

P = pressure, atm

V = volume, L

n = moles, mol

R = gas constant = 0.08206 (L·atm)/(mol·K)

T = temperature, K
