1.) 2 methylpropene is a compound used to make synthetic rubber. A sample of 2 methylpropene contains 0.566 g C and 0.0933 g H. Determine its empirical formula

1 answer

mols C = grams/atomic mass = ?
mols H = grams/atomic mass = ?

Now find the ratio of the two elements to each other with the smaller number being no less than 1.00. The easy way to do is to divide BOTH numbers by the same small number,then multiply both numbers by any number to produce a whole number for C and a whole number for H. That is multiply by 2, 3, 4, etc until you get two whole numbers. The answer here is CH2.
