Question

a solution weighing a g has molality b. the molecular mass of solute if theass of solutecc g will be​

Answer 1

Answer:Let x be the molar mass of the solute

No. Of moles of solute = a/x = M(let)

According to the formula for molality,

(M x 1000)/c = b

>> M = bc/1000

>> a/x = bc/1000

>> x = (1000a)/bc

Hence molar mass of the substance is (1000a)/bc
