Question

qual a massa correspondente a 112l de co,nas cntp? me ajudeeem por favor!

Answer 1

Se :

1 mol CO ----------- 22,4 L
x mol CO ------------ 112 L

x = 112 * 1 / 22,4

x = 112 / 22,4

x = 5,0 mols CO

Então :  

Massa molar CO => 28,0 g/mol

1 mol CO ---------- 28,0 g
5,0 mols CO -------- m

m = 5,0* 28,0 / 1

m = 140 g de CO
