dissolved in 50g of water.

Answer 1

28.57 is the crrt ans...

Answer 2

Dear Student,

◆ Answer -

Concentration (w/w) = 28.57 %

● Explaination -

# Given -

Weight of common salt = 20 g

Weight of water = 50 g

# Solution -

Concentration of solution by weight percent is calculated by -

Concentration = weight of salt × 100 / (weight of salt + weight of water)

Concentration = 20 × 100 / (20 + 50)

Concentration = 28.57 %

Therefore, concentration of solution (w/w) is 28.57 %.

Thanks dear. Hope this helps you...
