Question

Calculate the concentration of salt in its solution with water. Amount of salt = 20g.
Amount of solution= 200(ml).
Plz give right solution and No spam plz dear.​

Answer 1

Answer:

HI

Explanation:

20 g of salt

in 200 ml of water

c=20/200

=0.1g per ml is the concentration of salt in water

Or 10 % of salt in water

Answer 2

Mass of solute (salt) = 20g

Mass of solvent (water) = 200 ml

The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution. If you have a small concentration, find the answer in parts per million (ppm) to make it easier to follow.

V= 200 + 20

V = 220 grams.

C = m/V,

Concentration = mass of solute/mass of solution x 100

Concentratin = 20/220 ×100

= 10℅
