Step 1

The combustion reactions are a type of chemical reactions where hydrocarbons react with oxygen and result in the production of water and carbon dioxide.

Step 2

The number of moles of a given chemical species is defined as the ratio of mass to the molar mass of the substance. The mathematical formula is as shown below:

Step 3

The mass of the unknown compound is given to be 0.7549 g.

It burns to form 1.9061 g of carbon dioxide gas and 0.3370 g of water.
