The question is : Using benzoic acid's solubility data in water (found in pre-lab), calculate the amount of hot water needed to dissolve your crude benzoic acid. Based on your data and observation, explain why you may have used more ore less water than the calculated value.   Pre lab Question: calculated amount of hot water to dissolve 2.0g of benzoic acid. => (2.0g benzoic acid)/( 68 g/L)(1000ml)/(1L) = 29.4 mL of hot water needed to dissolve 2.0g of benzoic acid. My cruse of benzoic acid is 1.81g.
