If 0.250 mol of hydrogen gas occupies 0.333L at 20.0c what is the pressure in atmospheres?

maria [59]

Answer: The pressure will be 18.05 atm.

Explanation: Expression for ideal gas equation is :

$PV=nRT$

where,

P = Pressure of the gas = ? atm

V = Volume of the gas = 0.333L

n = Number of moles of gas = 0.250 moles

R = Universal gas constant = $0.082057\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the gas = 20°C = (273 + 20)K = 293K

Putting values in above equation, we get:

$P\times 0.333L=0.250mol\times 0.082057\text{ L atm }mol^{-1}K^{-1}\times 293K$

P = 18.05 atm
