PASSAGE-II : The percentage composition of elements in a compound is calculated from the molecular formula of the compound. The molecular mass of a compound is calculated from the atomic masses of the various elements present in the compound. The percentage of mass of each element is then calculated by the help of the following relation. Percentage mass of the element in the compound `=("Mass of the element")/("Mass of the compound") xx 100`

A

28

B

56

C

65

D

75

Text Solution

Verified by Experts

The correct Answer is:
A
