Suppose you have 4.832 g of product and then rinse it with 20.0 mL of 4°C water, use the answer in 2c to calculate how much product would you expect to isolate. e. Using your answers from (b) and (d), calculate the percent error or percent difference as a result of accidentally using the 25°C water, water that is too warm, compared with the correct (accepted) yield isolated using 20. mL of 4°C water.
