Question

How many grams of sugar is required to prepare 5% W/V sugar in 2 litre aqueous solution

Answer 1

The formula for weight percent (w/v) is: [Mass of solute (g) / Volume of solution (ml)] x 100

Here, (w/v) is 5%.
Volume of aqoeus solution, V: 2litre.
So, weight of solute: (5*2000)/100 = 100 grams
