Question

Calculate the percentage of Oxygen in Ca(OH)2

Answer 1

Answer:

The atomic mass of Ca is 40.1 g/mol.

The molar mass of Ca(OH)

2

=74g/mol.

1 mole of Ca(OH) 2

= 74 g Ca(OH) 2

=40.1 g Ca

The percentage composition of calcium in calcium hydroxide = 40.1*100/74

=54%

Answer 2

Answer:

The atomic mass of Ca is 40.1 g/mol.

The molar mass of Ca(OH) 2 =74g/mol.

1 mole of Ca(OH) 2 = 74 g Ca(OH) 2=40.1 g Ca

The percentage composition of calcium in calcium hydroxide = 40.1×100/74= 54%
