Question

calculate mole fraction of HCL in solution of HCL containing 24.8 percent of HCL by mass​

Answer 1

Let us assume total given mass = 100g

Now, we have 24.8g of HCl.

Molecular mass of HCl = 36.45g.

No. of moles = 24.8 / 36.45 = 0.68 moles

Volume of water we have = 100-24.8 = 75.2g

Moles of water we have = 75.2 / 18 = 4.18 moles

MOLE FRACTION OF HCl = (Moles of HCl) / (Total moles) = 0.68 / (0.68+4.18)

= 0.14
