Question

10% M/M solution contains 10 gm solute,dissolved in ............. solvent.
(a)100gm (b)90gm(c)80gm (d)110gm

Answer 1

Answer:

c) Mass of Solvent =90  grams

Explanation:

A solution is produced from a solute and a solvent.

The amount of solute is a lot lesser than the amount of solvent.

Let the mass of the solution be 100g

∴Mass of solute will be 10g

Hence the mass of the solvent will be;

M(solution) = M(Solute) + M (Solvent)

∴Mass of Solvent = 100-10.

∴Mass of Solvent =90  grams

Answer 2

As per the data given

Mass of solute = 10gm

Let the mass of the solution be x gm

According to the question

10% of x = 10

⇒ x = 100 gm

Mass of the solution = 100gm

Now

Mass of the solution = Mass of the solute + Mass of the solvent

⇒ 100 = 10 + Mass of the solvent

⇒ Mass of the solvent = 100-10 =90 gm

Hence 10% M/M solution contains 10gm solute, dissolved in 90 gm solvent.
