Answer 1

Question : How will you prepare a 12% solution of sugar.

Answer :

We can prepare a 12% sugar solution by adding 12 grams of sugar in 88 grams of water.

We know that, concentration by mass, or mass by mass percentage =

$\sf\frac{mass \ of \ solute}{mass \ of \ solution} \times 100$

So, if we will take 12 gram of sugar, then mass of solute = 12 g

and mass of solution = mass of solute + mass of solvent = 12 + 88 = 100 g

So, percentage = 12/100 × 100

= 12%

Hence, to prepare a 12% sugar solution, we need to add 12 grams of sugar in 88 grams of water.
