A compound is found to contain 63.65 % nitrogen and 36.35 % oxygen by mass. The molar mass for this compound is 44.02 g/mol. The molecular formula for this compound is

THE MOLECULAR FORMULA FOR THE COMPOUND IS N20

Explanation:

To calculate the molecular formula for the compound, we follow the following steps:

Write out the percentage abundance of the individual elements

N = 63.65 %

O = 36.35 %

2. Divide the percentage composition by the atomic masses of the elements

N = 63.65 / 14 = 4.546

O = 36.35 / 16 = 2.272

3. Divide the values by the lowest value

N = 4.546 / 2.272 = 2.00

O = 2.202 / 2.272 = 1

4. The empirical formula of the compound will be:

N2O

5. Calculate the molecular mass

(N2O ) x = 44.02 g/mol.

(14 * 2 + 16) x = 44.02

(28 + 16) x = 44.02

44 x = 44.02

x = 44.02 / 44

x = 1

The molecular formula for the compound is N2O
