Sagot :
Answer:
CH2
Explanation:
We are given that a compound is 14.40% hydrogen and 85.60% carbon.
Let the mass of the substance be 100g.
Mass of the hydrogen: 14.40% of 100 = 14.40 g
Mass of the carbon: 85.60% of 100 = 85.60 g
Now, let's find the moles of hydrogen:
[tex]14.40 g*\frac{1 mole}{1gH} = 14.40 mole[/tex]
Moles of carbon:
[tex]85.60g*\frac{1 mol}{12gC} = 7.13mol[/tex]
Let's put these in a ratio and simplify:
7.13 mole C: 14.40 mole H
1 mole C: 2 mole H
Therefore, the empirical formula of this compound is CH2.
