Question

Halla el volumen ocupado por 35 gramos de NH3 a 40°c y 3atm

Answer 1

Ley de los gases ideales

V P  = n R T

R = 0.0821 (L atm/mol K)
T = 40 ºC + 273 = 313 K
P = 3 atm
n = mol
Mm NH3 = 17 g/mol
n = masa/Mm
n = 35 g / 17 g/mol
n = 2.058 mol

calcular V = n R T / P

V = 2.058 mol x 0.0821 (L atm/ mol K) x 313 K

V = 17.62 L
