Question

Determine the empirical formula for a compound that is made from 1. 967g of carbon, 0. 4115g of hydrogen, and 2. 6205 g of oxygen. Put the formula in the order of carbon then hydrogen then oxygen. (Show work on scratch paper and upload in the last question. Write the formula without subscripts. For example C3H8O2 would be written C3H8O2)

Answer 1

CH4 the answer

Step-by-step explanation:

The compound is found to be composed of 75% carbon and 25% hydrogen.

100 g of the compound contains 75 g of carbon and 25 g of hydrogen.

The atomic masses of carbon and hydrogen are 12 g/mol and 1 g/mol respectively.

The number of moles of C = 12 g/mol 75 g = 6.25 moles

The number of moles of H = 1 g/mol 25 g = 25 moles

The mole ratio C:H=6.25:25=1:4

The empirical formula of the compound is CH4.
