Question

18 gram of sucrose is dissolved in 162 gram of water calculate the mass percentage of solution

Answer 1

Answer:

18g=Mass of solute

162g=Mass of solvent

162+18=180g=Mass of solution

Concentration= Mass of solute/Mass of solution

18/180

10%

Explanation:

Answer 2

Answer:

The given solution's mass percentage calculated is $10\%$.

Explanation:

Data given,

The mass of sucrose ( solute ), $m_{solute}$ = $18g$

The mass of water ( solvent ), $m_{solvent}$ = $162g$

The mass percentage of solution =?

As we know,

• Mass percentage ( W/W % ) = $\frac{m_{solute}}{m_{solute} + m_{solvent}}\times 100$

After putting the value of masses of solute and solvent in the equation. we get:

• Mass percentage ( W/W % ) = $\frac{18}{18+162}\times 100$
• Mass percentage ( W/W % ) = $\frac{18}{180}\times 100$ = $10\%$

Hence, the solution's mass percentage calculated is $10\%$.
