Question

0.5g of salt is dissolved in 25g of water.calculate the percentage amount of the salt in the solution?????

Please help

Answer 1

I have solved this question just now but once again for u.

Solute= 0.5g Solvent = 25g so solution = 25.5g

concentration = (0.5/25.5)×100
= 1.98% approx

Answer 2

Answer:

2℅

Explanation:

Mass of solute (salt) = 0.5 g

mass of solvent (water) = 25g

we know,

Mass of solutions =Mass of solute + Mass of solvent

=0.5 g 25 g

=25.5 g

Mass percentage of solution

=Mass of solute x 100

mass of solution

= 0.5 x100 = 2℅

25
