Question

Alex added 10g of salt to 90g of water. What is the percentage of salt in this solution now?

Answer 1

10 percent

Explanation:

Answer 2

10%

Explanation:

Amount of salt in 90g of water = 10g

Total weight of solution (salt + water) = (10g + 90g) = 100g

=> Total weight of salt in 100g of solution = 10g

Hence, Percentage of salt in this solution is given by:

`\[(10)/(100)*100\]`

This corresponds to 10%

So the percentage of salt in the solution = 10%

Similarly, percentage of water in the solution =
`\[(90)/(100)*100\]` = 90%
