Question

a solution contains 50 gram of common salt in 450 grams of water. calculate the concentration of the solution in terms of the mass by mass percentage.​

Answer 1

Answer: 10%

Step by step explanation:

Given,

➡️ The mass of the common salt= 50 g

➡️ The mass of water = 450 g

=> The total mass of solution = mass of salt + mass of water

Therefore,

Total Mass of Solution

=> 50 g + 450

=> 500 g

▪️ We have to find, concentration of solution.

⏺️ According to the formula of concentration of solution:

=> Concentration of solution = Mass of solute/Mass of solution × 100

=> Concentration of solution = 50/500×100

=> Concentration of solution = 10%

Therefore,

◼️ Concentration of solution is 10%

Answer 2

$\bf\huge{SOLUTION:-}$

From the question,

i)Mass of common salt=50 gm

ii)Mass of water = 450gm

>Total mass of the solution=

Mass of common salt+Mass of water

>50gm+450gm=500gm

Formula to find concentration of a solution in terms of mass by mass percentage is :-

Mass of solute/Mass of solution×100

=50÷500×100

=10%

Therefore, Concerntration in terms of mass by mass percentage is 10%
