an organic compound having molecular mass 294 contain 14 point 92% carbon 54 point 50% Oxygen and 4.58 percent hydrogen determine the empirical formula and molecular formula of the compound​

Explanation:

Answer 2

Explanation:

Vitamin C contains 40.92% carbon by mass, 4.58% hydrogen and 54.50% oxygen.

100 g of vitamin C will contain 40.92 g C, 4.58 g, H and 54.50 g O.

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

The number of moles of C=

12 g/mol

40.92 g

=3.4 mol.

The number of moles of H=

1 g/mol

4.58 g

=4.58 mol.

The number of moles of O=

16 g/mol

54.50 g

=3.40 mol.

The mole ratio C: H : O = 3.4 : 4.58 : 3.4 = 3 : 4 : 3

The empirical formula of vitamin C is

C3H4O3.
