Answer 1

Answer:

6 %

Explanation:

divide 120 by 20

by formula

Answer 2

Answer :

Mass of solute = 20g

Mass of solvent = 100g

We have to find mass percentage of sugar solution$.$

Definition : Amount of solute in grams present in 100g of solution.

Symbol : %(w/W)

Effect of temperature : No effect

Formula :

• %(w/W) = m₁ / (m₁ + m₂) × 100

m₁ denotes mass of solute

m₂ denotes mass of solvent

By substituting the given values, we get

➠ %(w/W) = m₁ / (m₁ + m₂) × 100

➠ %(w/W) = 20/(20+100) × 100

➠ %(w/W) = 2000/120

➠ %(w/W) = 16.67%
