Answer 1

Answer:

fnd the solvent and the solute from that.

Explanation:

270/30×100=?

find the rest answer

Answer 2

Given : A solution contains 30 g of common salt in 270 g of water.

　

To find : Calculate the concentration of solution?

　

Applying formula :

1) Mass of solution = Mass of solute + Mass of solvent.

2) Mass percentage = Mass of solute/Mass of solution × 100.

　

Calculations :

→ Mass of solution = 30 + 270

→ Mass of solution = 300

　

→ Mass percentage = 30/300 × 100

→ Mass percentage = 0.1 × 100

→ Mass percentage = 10%

　

Therefore, 10% is the mass percentage of the solution.
