Answer:
N2O3
Step-by-step explanation:
The empirical formula of a compound can be calculated as follows:
N = 36.86% = 36.86g
O = 63.14% = 63.14g
First, we divide each value by its molar mass as follows:
N = 36.86g ÷ 14g/mol = 2.63mol
O = 63.14g ÷ 16g/mol = 3.95mol
Next, we divide by the smallest mole value;
N = 2.63mol = 2.63 = 1
O = 3.95mol ÷ 2.63 = 1.5
We multiply each value by 2 to get an approximate whole number ratio i.e. N = 2, O = 3
