Question

Determine the volume, in liters, occupied by 0.080 moles of a gas at STP.

Answer 1

V = 1.79 L

Step-by-step explanation:

Given data:

Volume of gas = ?

Number of moles of gas = 0.080 mol

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

1 atm × V = 0.080 mol × 0.0821 atm.L/ mol.K × 273.15 K

V = 1.79 atm.L / 1 atm

V = 1.79 L
