Stoichiometry tells us the expected amount of product. Percent yield is taking the amount received in the lab (observed) and dividing it by the expected amount. 

A chemist was challenged with making an exact amount of aluminum hydroxide in order to make an order for some antiperspirant. They were given 10.0 grams of calcium hydroxide and all the aluminum nitrate necessary. After completing the experiment, filtering out the precipitate, and drying the compound, the chemist was only able to isolate 6.0 grams of aluminum hydroxide. Determine the expected amount of aluminum hydroxide, the percent yield, and percent error of this chemist?

The balanced equation is below:
 

Round all answers to whole numbers.
The expected amount of aluminum hydroxide is _______ grams. 
The percent yield of the experiment is _______ %.
The percent error of the experiment is _______ %.
