Answer:
B
101L
Explanation:
We use the ideal gas relation
PV = nRT
P = pressure = 101.3KPa
V = volume = ?
n = number of moles = 4.5moles
T = Temperature = 273.15K
R = molar gas constant = 8.314J/mol.k
Rearranging the equation to make V the subject of the formula yields :
V = nRT/P
= ( 4.5 × 8.314 × 273.15) ÷ 101.3
= 10,219.361 ÷ 101.3 = 100.88L which is apprx 101L
