Question

Table salt has a solubility of 36g of salt in 100g of water at 40 degrees celcius. If 15g of salt is added to 50g of water at the same room temperature, is the resulting solution saturated of unsaterated? Explain your answer.
The solubility is 36 g/100. So what's the solubility in 50 g? That's 36 g salt x (50/100) = 18 g. You have 15 g to put in the 50 g H2O. So will that be saturated or not?
