Question

Table salt has a solubility of 36 g of salt in 100 g of water at 40°C. If 15 g of the salt are added to 50 g of water at the same temperature, is the resulting solution saturated or unsaturated? Explain please

Answer 1

36 g salt ---> 100 g water
x g salt ----> 50 g water

Simple ratio-proportion.

so,

36 100
-- = ---
x 50

Now if x is greater 15 g of salt (that you added), then it's unsaturated.
