Find the volume of 56 g dinitrogen at STP

Options

A11 2 Lit
B22 4 Lit
C44 8 Lit
D67 2 Lit

Correct answer

C. 44 8 Lit

Step-by-step solution

The molar mass of dinitrogen (N 2 ) is 28 g/mol , calculated from the atomic mass of nitrogen (14 g/mol). The number of moles in 56 g of dinitrogen is n = 56 28 = 2 moles. At STP, one mole of gas occupies 22.4 liters, so the volume is 2 22.4 = 44.8 liters. The volume of 56 g of dinitrogen at STP is 44.8 liters.
