March 4--Stoichimetry Calculation

Part 1: Moles and Mass

For example,


Given equation:

I2 + F2  produced   IF5 + I4F2

How many grams of I4F2 are produced by 5.40 mol of F2?

Step1 : Balance the equation

3 I2 + 6 F2 produced 2 IF5 + I4F2

Step 2:Make a map

5.40 mol of F2 ----- to ------ ? grams of I4F2

                  mole I4F2 

Step 3:Do calculation

5.40 mol F2* (1 mole I4F2/ 1 mole F2)* (545.6g of I4F2/1 mole of I4F2)

= 2950g of I4F2
