Carlos is making phosphorus trichloride using the equation below. He uses 15.5 g of phosphorus and collects 50.9 g of phosphorus chloride.

2P +3Cl2 → 2PCl3

How much chlorine reacted with the phosphorus?

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

Explanation :

First we have to calculate the moles of phosphorus.

Now we have to calculate the moles of

The balanced chemical reaction is:

From the balanced chemical reaction, we conclude that

As, 2 moles of phosphorous react with 3 moles of

So, 0.5 moles of phosphorous react with moles of

Now we have to calculate the mass of

Molar mass of = 71 g/mol

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

did anyone actually do this? like if anyone has submitted this i rly need .
