What is the volume of 14.0 g of nitrogen gas, \([tex]N_2[/tex]\), at a pressure of 2.00 atm and a temperature of 27.0 degrees Celsius?

A. 5.60 L
B. 6.15 L
C. 11.2 L
D. 12.3 L

Answer (3)

p = 2.00 atm = 2026.50hPa T = 27°C = 300K m = 14.0g | Mr = 28g/mol | n = m/M = 14g/28g/mol = 0,5mol R = 83.1 [hPa L]/[mol K]
pV = nRT
nRT 0,5mol * 83.1[hPa L]/[mol K] * 300K V = ---------- = ----------------------------------------------------------- = 6.15L p 2026.5hPa
Answer B.
