9. What is the volume occupied by 2.75 moles of N2 gas at STP?

Question

Question

Answer 1

Answer #1

Answer

61.6L

Explanation

Ideal gas equation is

PV = nRT

P = Pressure, 1atm

V = Volume , ?

n = number of moles, 2.75mol

R = gas constant , 0.082057(L atm/mol K)

T = Temperature, 273.15K

V = nRT/ P

= 2.75mol × 0.082057(L atm/ mol K) × 273.15K/ 1atm

= 61.6L
