What is the mass and # of molecules of PCl3 formed in the reaction of 75.0 g P4 with 275 g Cl2 ?

The mass of PCl₃ is 332.3 g.

The molecules of PCl₃ is

Explanation:

Given that,

Mass of P₄ = 75.0 g

Mass of Cl₂ = 275 g

We know that,

The reaction is

We need to calculate the moles of P₄

Using formula of moles

Put the value into the formula

We need to calculate the moles of Cl₂

Using formula of moles

Put the value into the formula

We need to calculate the number of moles of

Moles in 1 P₄ = 0.61

So,

We need to calculate the mass of

Using formula of mass

Put the value into the formula

We need to calculate the molecules of

Using formula of molecules

Where, n = number of moles

N = avagadro number

Put the value into the formula

Hence, The mass of PCl₃ is 332.3 g.
