Question

Concentrations of solution is 8% ( w/w) and 10% (w/v) calculate the density of a solution

Answer 1

Answer: -

1.25 g / mL

Explanation: -

Concentration (w/w) is 8%.

This means that 8 g of the solute is present in 100 g of solution.

Again concentration (w/v) = 10%

But weight of solute is 8 g.

Volume of solution = 8 x 10 = 80 mL

Density of solution = $\frac{Mass of solution}{Volume of solution}$

= $\frac{100g}{80mL}$

= 1.25 g /mL
