how many grams of carbon monoxide are needed to react completely with 16 grams of oxygen gas? 2 CO (g) + O2(g) → 2 CO2 (g)

Respuesta :

Willchemistry
Molar mass :

O2 = 31.99 g/mol
CO = 28.01 g/mol

2 CO (g) + O2(g) =  2 CO2 (g)

2 x 28.01 g CO -------------------- 31.99 g O2
mass CO --------------------------- 16 g O2

mass CO = 16 x 2 x 28.01 / 31.99

mass CO = 896.32 / 31.99

=> 28.018 g of CO
