Question

find out the empirical formula and molecular formula in organic compound contains 62.07 %carbon 10% hudrogen and 14% of nitrogen molecular mass is 114g​

Answer 1

ANSWER

100 g of compound will contain 62.07 g of C, 10.34 g of H, 14.0 g of N and 13.59 g of O.

The atomic masses of C, H, N and O are 12 g/mol, 1 g/mol, 14 g/mol and 16 g/mol respectively.

The number of moles of C =

12 g/mol

62.07 g

=5.17 mol.

The number of moles of H =

1 g/mol

10.34 g

=10.34 mol.

The number of moles of N =

14 g/mol

14 g

=1 mol.

The number of moles of O =

16 g/mol

13.59 g

=0.85 mol.

The mole ratio C:H:N:O=5.17:10.34:1:0.85≃5:10:1:1

Hence, the empirical formula is C

NO

The empirical formula mass =5(12)+10(1)+14+16=100 g/mol

The ratio of molecular formula mass to empirical formula mass =

100

144

=1.44

Hence, the molecular formula of organic compound is (C
