Question #223529

A compound is found to contain **15.12** % **phosphorus**, **6.841** % **nitrogen**, and **78.03** % **bromine** by mass.

Expert's answer

**Solution**

**P= 15.21%**

**N=6.841%**

**B=78.03%**

**Molar mass P=0.4881,N=0.4884,B=0.97**

**divide by the smallest number**

"P=\\frac{0.4881}{0.4881}=1"

"N=\\frac{0.4884}{0.4881}=1"

"B= \\frac{0.9765}{0.4881}= 2"

Empirical formula Br_{2}NP
