Methylpropene is used to make synthetic rubber and
contains 0.556g carbon, 0.0933g hydrogen. What is the empirical formula?


Sagot :

Answer:

CH₂

Explanation:

First we convert the given masses of elements into moles, using their respective molar masses:

  • C ⇒ 0.556 g ÷ 12 g/mol = 0.0463 mol C
  • H ⇒ 0.0933 g ÷ 1 g/mol = 0.0933 mol H

Now we divide those results by the lowest value between the two of them:

  • C ⇒ 0.0463 / 0.0463 = 1
  • H ⇒ 0.0933 / 0.0463 = 2

Meaning the empirical formula is CH₂.
