Question

1) solid liquid 2) liquid - solid 3) liquid - liquid 4) solid - solid
60 g of common salt present in 400g of solution, the concentration of solution will be
1) 13.4%
2) 10%
3) 15%
4) 13%​

Answer 1

Answer:

$13.4$

solution

The formula for the % calculation:

percentage by mass = mass of solute  x 100% (mass of solute = 60g

                                 mass of solution            mass of solution= 60g+400g=460)

  

% concentration = 60g   x 100%  =  6000    =13.04%

                           460g                    460

percentage concentration = 13.04%

here is the correct answer please mark me brainliest and give thanks

Answer 2

Answer:

Explanation:

Answer:Volume = 50cm cube

Mass = 400g

Density?

Density = Mass /Volume

= 400/50

= 8 g/cm^3
