You are watching: What is the percent composition of calcium ca in cao

muzic-ivan.info:

C 40 g/56 g × 100 %

Explanation:

Calculate the mass of each component and also the full mass.

Element Atomic mass/u No. of atoms Subtotal mass/u

Ca 40.08 1 40.08

O 16.00 1 16.00

Total = 56.08

The formula for mass percent is

% by mass = Mass of component/Total mass × 100 %

In this problem

% Ca = mass of Ca/mass of CaO × 100 %

% H = 40.08 g/56.08 g × 100 %

Explanation:

In the given equation 1 molecule of Lithium reacts with 1 molecule of chlorine gives Lithium Chloride as a product.

For balancing an equation the variety of atoms of each aspect of reactant have to be equal to the variety of atoms of each aspect of product.

Here one atom of Lithium reacts via 2 atom of of Chlorine and produces Lithium Chloride.

For balancing we have to multiply Lithium by 2 and also Lithium Chloride by 2.

So after balancing the variety of atoms of 2 molecule of Lithium is 2 and of Chlorine is 2 and also of the product Lithium Chloride is also 2.

Hence the given equation is well balanced.
