Question

a solution contains 40gram of common salt in 480gram of water calculate the concentration

Answer 1

Answer:

4.54%

Explanation:

Mass of solute=40g

Mass of solvent=480g

Mass of solution=(Mass of solute + Mass of solvent)

Mass of solution=40+480

=880

Mass%=Mass of solute

Mass of solution

Mass%= 40 × 100

880

= 4 ×100

88

= 1 × 100

44

= 100

44

= 50

11

Mass%=4.54
