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.

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 H2 (g) + 1 O2 (g) ---> 2 H2O1 (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 13.7g 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)
