Explanation:

To determine the density, use the following equation. 

Density = Mass of 1 mole ÷ Volume of 1 mole 

At STP, the volume of one mole of a gas is 22.4 liters. Let’s use the following equation to determine the volume of mole at 127°C and 3.5 atmosphere. 

P1 * V1/T1 = P2 * V2/T2 

P1 = 3.5, T1 = 127 + 273 = 400, P2 = 1, V2 = 22.4, T2 = 273

3.5 * V1/400 = 1 * 22.4/273 

V1 = 400/3.5 * 22.4/273 = 9.377289377 

To determine the density, use the following equation. 

Density = 16 ÷ 9.377289377 = 1.70625 g/L
