Please Help Me I Would Greatly Appreciate It I Will Mark Brainliest And Give 50 Points class=

Answer :

Answer: 72.07%

Explanation:

P4 + 6 Cl2 --> 4PCl3

Since 123.90g/mol P4 is equivalent to 4(137.33g/mol PCl3)

So, 79.48g P4 = 4(137.33g/mol)(79.48g)/(123.90g/mol)

= 352.38g PCl3 formed

Percentage yield = (253.9/352.38) * 100 = 72.07%
