Express your answer to three significant figures and include the appropriate units?

2-Part B

In the Sandwich Shop, select the "Cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich.

In the equation, set the number of bread slices to "2" and the number of cheese slices to "1." You will see that the product formed by these three ingredients is one cheese sandwich.

Suppose you have 48 bread slices and 38 cheese slices. How many cheese sandwiches can you make?

Express your answer as an integer.

Explanation / Answer

A)2Al+3Cl2---->2AlCl3

From the equation it is clear that 3 moles Cl2 produces 2 moles AlCl3

36 gm Cl2=36/71=0.507 moles

So moles of AlCl3 produced=(2/3)(0.507)

=0.338

So mass of AlCl3 produced=No of moles x Molar mass

=(0.338)(133.34)

=45.068 gm

B)Each cheese sandwich contains 2 bread slices and one cheese slice

No of bread slices available=48

No if cheese slices available=38

Here bread slices are limited

So we can make (48/2)=24 cheese sandwiches

No of cheese slices remaining=38-24=14
