1) Determine how the following error would affect calculated the percent yield of alum. (increase, decrease, no effect). Briefly explain.

- Alum Sample was not dried completely in the oven.

Solutions

Expert Solution

Since alum was not dried in oven it will be having water molecules with it. Hence it will be more weight than actual weight.

While you calculate the percentage yield according to eq 4 (down) it will give increased yield because of water molecules presence with alum

Answer is Increased percentage yield

Following way you can calculate yield
