1. One mole of an unknown compound has 36.0 g of carbon and 6.0 g of hydrogen. What
is the empirical formula of the unknown compound? (Hint: You will want to reduce to find
the empirical formula)
Given: Carbon: 36.0 grams
1 mol C = 12.0 g
Hydrogen: 6.0 g
1 mol H = 1.0 g
Unknown: empirical formula
Solve:

Answer 1

CH2

Step-by-step explanation:

The empirical formula is the simplest formula of a chemical compound. It shows the ratio in which constituent atoms are combined in the compound.

To obtain the empirical formula, we divide the given mass of each element by the relative atomic mass of that element.

C- 36.0 g/12.0 g H- 6.0g/1.0g

C- 3 H-6

Divide through by the lowest ratio;

C-3/3 H- 6/3

C-1 H-2

Hence the empirical formula of the compound is

CH2
