Question 13

Phosphorus reacts with chlorine to form a phosphorus chloride compound.

A sample of this phosphorus chloride contains 3.1 g of phosphorus atoms and 10.65 g of chlorine atoms.

Calculate the empirical formula of this sample of phosphorus chloride. (Relative atomic masses, $ArA_{\text{r}}$ : $P=31\text{P} = 31$ , $Cl=35.5\text{Cl} = 35.5$ )
