Question

a solution contain 35g of common salt in 300g of water. calculate the concentration of the solution.
plz give right answer .
I ll mark u brainliest​

Answer 1

Answer:

10.45%

Explanation:

Calculate the concentration of the solution. Concentration of solution = (35g)(335g)×100=10.45%.

Answer 2

Answer:

1.99 M

Explanation:

Molarity(concentration) =no of moles/volume of solution

No of moles of comman salt = 35grms/58.5grms

=0.5982

Now 300grms of water =300ml of water (density=1grm/ml)

There for MOLARITY = 0.5982/0.3L

= 1.99M

If u take molality then it would be =1.99m
