of carbon and of hydrogen is present in the given compound.
Further Explanation:
Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.
Consider the mass of the compound to be 100 g.
The formula to calculate the mass of carbon in the compound is calculated as follows:
…… (1)
The % of carbon in the compound is 88.14 %.
The mass of the compound is 100 g.
Substitute these values in equation (1).
The formula to calculate the mass of hydrogen in the compound is calculated as follows:
…… (2)
The % of hydrogen in the compound is 11.86 %.
The mass of the compound is 100 g.
Substitute these values in equation (2).
The formula to calculate the moles of carbon is as follows:
(3)
The given mass of carbon is 88.14 g.
Molar mass of carbon is 12 g/mol.
Substitute these values in equation (3).
The formula to calculate the moles of hydrogen is as follows:
…… (4)
Given mass of hydrogen is 11.86 g.
Molar mass of hydrogen is 1 g/mol.
Substitute these values in equation (4).
