Question

A solution is prepared by dissolving $11g$ glucose in $250c{m}^3$ water at ${30}^{o}C$. what is mass percent glucose in solution. The density of water at ${30}^o$ is $0.996g/c{m}^3$.

Answer 1

Mass%=$100$ $\times$ mass of solute/mass of solution

Mass of solute $=$ $11g$

Mass of solution $=$ $11+0.0996$

Mass% $=$ $11\times 100/11.0996=99.10$
