Question

A 33 g of sucrose solution is dissolved 350 g of teacup of 80⁰C water. Find the % m/v of

solution. Assume that the density of solution is 1.12 g/mL

Answer 1

Density of solution$=\frac{Total mass}{Volume}=\frac{M}{V}$

$M=33g+350g=383g$

$\frac{383}{V}=1.12$

$V=\frac{383}{1.12}=341.96$

$\%of\frac{M}{V}=\frac{383}{341.96}×100=112\%$
