Answer 1

Answer:

Mass of sodium chloride = 26.25 g

Mass of water = 147.75 g

Explanation:

Mass% = (grams of solute)/(grams of solution) × 100

Here,

Mass% = 15%

Grams of solution = 175 g

Let the grams of sodium chloride be x.

15 = × 100

⇒ x = (15 × 175)/100

⇒ x =

⇒ x = 26.25 g

∴ Mass of Water = Total mass - Mass of sodium chloride

Let the mass of water be y.

⇒ y = 175 - 26.25

⇒ y= 147.75 g

∴ Mass of sodium chloride = 26.25 g

∴ Mass of water = 147.75 g
