Question

acetone boils at 56.38 c and a solution of 1.41 g of an organic compound in 20g of acetone boils at 56.88 c .if kb for acetone is 1.67 K Kg mom calculate the mass of 1 mole of the organic solid​

Answer 1

Answer:

i think ans is help you thanks

Answer 2

The mass of 1 mole of the organic solid 235.47.

Explanation:

Δ$T_{b}=K_{b}*molality$

Δ$T_{b}=K_{b}*\frac{(mss of solute/molecular mass )*1000}{mass of solvent}$

$(56.88-56.38)=\frac{1.67*(\frac{1.41}{msolute})*1000 }{20}$

mass of solute(m)=235.47.
