Question

Assuming that 1 gram of aspirin dissolves in 450 ml of water at 10°C, how much aspirin would be lost in 40 ml of water added to the reaction mixture if the mixture were at 10 °C during filtration?

Answer 1

How much water is there initially? If none, then, aspirin lost is
1 g x (40 mL/450mL) = ?? grams.
If some water is present initially, then add 40 to it and place the total where 40 is in the above equation.

Answer 2

1g X (5ml/450ml)=0.01g

Answer 3

1gx5ml/450ml
