7. Refer to the example in Techniques section 1.3. Suppose you had a mixture consisting of 20.0 g of compound A and 20.0 g of compound B dissolved in 100. mL of water at 95°C. Suppose further that only 1.00 g of A are soluble in 100. mL of water at 5°C. but 15.0 g of B are soluble in 100. mL of water at 5°C. What is the mass ratio of A to B in the 95°C mixture before recrystallization? a.
