Question

If you start with 8.95 g of crude sulfanilamide and recrystallize it from ethanol to recover 7.20 g of pure sulfanilamide, what is the percent recovery

Answer 1

`\% rec=80.4\%`

Step-by-step explanation:

Hello!

In this case, since the percent recovery for this crystallization operation is computed as shown below:

`\% rec=(m_(recovered))/(m_(initial)) *100\%`

Thus, by plugging in the initial 8.95 g and the recovered 7.20 g, we obtain:

`\% rec=(7.20g)/(8.95g) *100\%\\\\\% rec=80.4\%`

Best regards!
