Carlos is making phosphorus trichloride using the equation below. He uses 15.5 g of phosphorus and collects 50.9 g of phosphorus
Oxana [17]

Answer : The mass of chlorine reacted with the phosphorus is, 53.25 grams.

Explanation :

First we have to calculate the moles of phosphorus.

\text{Moles of phosphorus}=\frac{\text{Mass of phosphorus}}{\text{Molar mass of phosphorus}}

\text{Moles of phosphorus}=\frac{15.5g}{31g/mol}=0.5mol

Now we have to calculate the moles of Cl_2

The balanced chemical reaction is:

2P+3Cl_2\rightarrow 2PCl_3

From the balanced chemical reaction, we conclude that

As, 2 moles of phosphorous react with 3 moles of Cl_2

So, 0.5 moles of phosphorous react with \frac{3}{2}\times 0.5=0.75 moles of Cl_2

Now we have to calculate the mass of Cl_2

\text{Mass of }Cl_2=\text{Moles of }Cl_2\times \text{Molar mass of }Cl_2

Molar mass of Cl_2 = 71 g/mol

\text{Mass of }Cl_2=0.75mol\times 71g/mol=53.25g

Therefore, the mass of chlorine reacted with the phosphorus is, 53.25 grams.
