Question

A solution is prepared by dissolving 96.4 g of RbI in enough water to form 865 mL of solution. Calculate the mass % of the solution if the density of the solution is 1.06 g/mL.

Answer 1

Answer:

The mass % of the solution is 10.51%.

Explanation:

Mass of solute i.e. RbI = 96.4 g

Volume of the solution = 865 mL

Mass of the solution = m

Density of the solution = d = 1.06 g/mL

$m=1.06 g/mL\times 865 mL=916.9 g$

The mass % of the solution:

$=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

$=\frac{96.4 g}{916.9 g}\times 100=10.51\%$
