Using the notes taken from, review of example of work from, PercentYield webpage, show all work to solve the following problems:

1) A baker is making chocolate cookies. He is following a recipe that should make 36 cookies. After baking the cookies, he actually has 24 cookies.

a) What is the actual/experimental yield of cookies?
b) What is the theoretical/stoichiometric yield of cookies?

c) What is the percent yield of cookies (show work here, round to 1st decimal place in percentage):

2) Instead of going to the bakery, we go to the chemical plant. Here they are making water from its elements following the balanced chemical equation:
2 H_{2 (g)} + 1 O_{2 (g)} ---> 2 H₂O_{1 (g)}
One run in the plant, 16.2g of Oxygen gas was consumed (assume have as much Hydrogen gas as needed). The process engineer determined that ##g of water was actually produced.

a) What is the actual/experimental yield of water?
b) What is the theoretical/stoichiometric yield of water? (show all appropriate work below)

c) What is the percent yield of water (show work here, round to 1st decimal place in percentage)
