First, find the number of moles for each element. The molar mass for nitrogen is 14 g/mol and that of hydrogen is 1 g/mol.
1.40 g N / 14 g/mol = 0.1 mol N
0.20 g H / 1 g/mol = 0.2 mol H
Find the mole ratio. Divide both numbers with the much lower value. In this case, it is 0.1 mol N.
For N: 0.1 ÷ 0.1 = 1
For H: 0.2÷0.1 = 2
Thus, the empirical formula is .

Explanation:
Given
(a) to (d)
Required
Determine whether the given parameters can calculate the required parameter
To calculate either Density, Mass or Volume, we have
(a) 432 g of table salt occupies 20.0 cm^3 of space
Here, we have:
The above can be used to calculate Density as follows;
(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3
Here, we have:
This can be used to solve for Volume as follows:
(c) 32 cm^3 sample of gold density of 19.3 g/cm^3
Here, we have:
This can be used to calculate Mass as follows:
(d) 150 g of iron, density of Iron = 79.0 g/cm^3
Here, we have
This can be used to calculate volume as follows:
