Answer:
10%
Step-by-step 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:
[tex]\[\frac{10}{100}*100\][/tex]
This corresponds to 10%
So the percentage of salt in the solution = 10%
Similarly, percentage of water in the solution = [tex]\[\frac{90}{100}*100\][/tex] = 90%
