Question

1.2 g of sucrose is added to water with the final volume of 75 ml. What is the concentration of sucrose in %w/v?

Answer 1

Answer:

16 g/L

Explanation:

Given that:-

Mass of sucrose added = 1.2 g

Volume of water = 75 mL = 0.075 L ( 1mL = 0.001 L )

%w/v is defined as the mass of the solution in 1 L of the solution.

So,

$\%\ w/v=\frac{Mass_{solute}}{Volume_{Solution}}$

$\%\ w/v=\frac{1.2\ g}{0.075\ L}=16\ g/L$
