Step 1

Given that the mass of CO2, H2O and NO is 3.939 g , 1.209 g and 4.028 g respectively.

The mass of Carbon, Hydrogen and Nitrogen can be calculated using the simple mole concept.

Step 2

Number of moles of Carbon, Hydrogen and Oxygen can be calculated by the equation given below:

Step 3

In-order to get the empirical formula, first the number of moles has to be divided with the lowest...
