After performing the calculation, we find that
. Therefore, the compound
is actually
, which is carbon dioxide.
Explanation
## Step 1: Understand the problemThe problem is asking us to find the number of oxygen atoms in the compound
given that the relative formula mass of the compound is 44. The atomic masses of carbon (C), oxygen (O), and hydrogen (H) are given as 12, 16, and 1 respectively.## Step 2: Formulate the equationThe relative formula mass of a compound is the sum of the atomic masses of all the atoms in the compound. In this case, the relative formula mass of
is the sum of the atomic mass of carbon and the atomic mass of oxygen multiplied by
. ###
## Step 3: Solve the equationWe can solve the equation for
by subtracting 12 from both sides and then dividing by 16.###
