Question

How much oxygen will add with 36 g carbon to give 132 g carbon
dioxide assuming complete combustion of carbon?​

Answer 1

Answer:48g

Explanation:

C + O2------> CO2

3mol+ x------>3 mol

Since the equation shows that the reactant and product are in equal amount, therefore 3mol O2 required

1molO2-------->16g

3molO2--------->48g

Answer 2

Answer:

96g

Explanation:

According to law of conservation of mass

Mass of carbon + mass of oxygen = Mass of carbon dioxide

  36 g                 +           x                 = 132g

so mass of oxygen =96 g
