Answer:
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.
The molecules of PCl₃ is
