Question

A solution is prepared by adding 2g of a substance a to 18 g of water calculate the mass percentage of solute

Answer 1

Explanation:

this is the solution

if it is correct tell me

Answer 2

Answer :

• Mass of solute = 2g
• mass of solvent = 18g

we need to find the mass Percent of solute

Mass % of solute = Mass of solute/mass of Solution × 100

• Mass of solute = 2g

Mass of Solution = 2g + 18g

Mass of Solution = 20g

Mass % of solute = 2g/20g × 100

= 2 × 5

= 10%

Hence,

• Mass percent of solute is 10%
