Question

calcula el volumen de 125,5g de oxido nitroso, N2 o, 95atm de presion y 13°c

Answer 1

Ley de los Gases Ideales

V · P = n · R · T

m = 125.5 g
Mm N2O = 44 g/mol
V = ?
P = 95 atm
T = 13 ºC + 273 = 286 K
R = 0.0821 (L atm / mol K)

1. calcular moles aplicando la fórmula n = masa/Mm
n = 125.5 g
     ````````````
       44 g/mol

n = 2.852 moles

2. calcular volumen

V = 2.852 mol · 0.0821 (L atm/mol K) · 286 K
       ``````````````````````````````````````````````````````````
                             95 atm

V = 0.705 L

mL = 0.705 x 1000 = 705 mL
