Question

A solution contains 25g of sugar in 225g of water. Calculate the concentration in terms of mass by mass percentage of the solution

Answer 1

Answer:

10 %

Explanation:

Given mass of solute = 25 g

and mass of solvent = 225 g

So mass of solution = mass of solvent +  mass of solute

Mass of solution = 25 g + 225 g = 250 g

$We \ know \ mass \ \%= (\dfrac{mass \ of \ solute}{mass \ of \ solution}) \times100\\\\\\putting \ values \ here\\\\\\\ mass \ \%=(\dfrac{25}{250})\times100\\\\\\ mass \ \%=10\\\\\\Thus \ mass \ percentage \ of \ the \ solution \ is \ 10\%$

Answer 2

Answer:

10 %

Explanation:

mass of solute = 25g

mass of solvent = 225g

mass of solution = 25 + 225 = 250g

mass / mass % = mass of solute / mass of solution × 100

= 25/250 × 100 = 10 %
