professor190 [17]3 years ago
5 0

Answer:

2.99 mol

Explanation:

Number of moles of CO₂ = ?

Volume = 67 L

Temperature and pressure = standard

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

By putting values,

1 atm × 67 L = n ×0.0821 atm.L/ mol.K × 273.15 K

67 atm.L = n×22.43 atm.L/ mol

n = 67 atm.L/22.43 atm.L/ mol

n = 2.99 mol
