Question

ayuda, necesito el procedimiento de este ejercicio

Answer 1

2 NaNO3 →2 NaNO2 + O2

Mm NaNO3 = 84.99 g/mol

O2 = 32 g/mol

1. convertir libras a gramos

1 libra ----- 453.59 g

0.45 libra ------ x

x = 204.12 g NaNO3

2. Calcular gramos de oxígeno

g O2 = 204.12 g NaNO3 x 1 mol NaNO3 x 1 mol O2 x 32 g O2 x 70 g

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

84.99 g NaNO3 2 mol NaNO3 1 mol O2 100 g

g O2 = 26.899
