Answer 1

m Zn = 100 g

MmZn = 65 g/mol

V = 100 g Zn  x  1 mol Zn  x   22,4 L H2

                          ``````````````````    ``````````````````````

                            65 g Zn      1 mol Zn

V = 34.46 L

CN

T = 273 K         P = 1  atm          R = 0.0821 (L atm / mol K)

Ley de los gases ideales

V x P = n x R x T

calcular moles de Zn

n = masa/Mm

n = 100 g / 65 g/mol

n = 1.538 moles

calcular Volumen

V = (1.538 mol x 0.0821 (L atm / mol K) x 273 K ) / 1 atm

V = 34.46 L
