Calculate the mass and amount of calcium substance reacted with 32 g of oxygen

Calcium enters into an oxidation reaction with oxygen. This reaction is described by the following chemical reaction equation:

Ca + ½ O2 = CaO;

During oxidation, one oxygen atom is attached to the calcium atom. In the course of the reaction, one molecule of calcium oxide is synthesized.

Let’s determine the chemical amount of oxygen.

To do this, we divide the available weight of oxygen by the weight of 1 mole of this substance.

M O2 = 32 grams / mol; N O2 = 32/32 = 1 mol;

In this reaction, a 2 times more chemical amount of calcium will react with oxygen.

Let’s calculate its weight.

N Ca = 1 x 2 = 2 mol; M Ca = 40 grams / mol; m Ca = 2 x 40 = 80 grams;
