The question is incomplete, the complete question is;

An unknown compound has the following chemical formula:

N2Ox

where x stands for a whole number.

Measurements also show that a certain sample of the unknown compound contains 3.7 mol of oxygen and 2.45 mol of nitrogen.

Write the complete chemical formula for the unknown compound.

Answer:

The complete formula of the compound is N2O3.

Step-by-step explanation:

Given;

Number of moles of N = 2.45 moles

Number of moles of O = 3.7 moles

Chemical formula of unknown compound = N2Ox

From the ratio of the number of moles of N to O;

2/x = 2.45/3.7

2 * 3.7 = x * 2.45

x = 2 * 3.7/ 2.45

x =3

Hence the complete formula of the compound is N2O3.
