Interpretation:
The formula of the nitrogen oxide containing 1.29 g of nitrogen and 3.71 g of oxygen needs to be determined.
Concept introduction:
To determine the formula of compound, find the mole number of each element of the compound.
Answer to Problem 7STP
The formula of the compound is
Explanation of Solution
Mass of nitrogen=1.29 g
Molar mass of nitrogen =
Mass of oxygen=3.71 g
Molar mass of oxygen =
To calculate the simplest ratio, divide number of moles of each element by the smallest number of moles, that is, 0.09.
Now,
So, the formula of the nitrogen oxide is
The formula of the compound can be find out from the mole number of each element of the compound. The formula of the nitrogen oxide is
