To determine the empirical formula of the compound given, we need to determine the ratio of each element in the compound. To do that we assume to have 100 grams sample of the compound with the given composition. Then, we calculate for the number of moles of each element. We do as follows:
         mass        moles
Sn     78.77       0.6636
O      21.23       1.3269

Dividing the number of moles of each element with the smallest value, we will have the empirical formula:

         moles                 ratio
Sn    0.6636          0.6636/0.6636 = 1
O     1.3269          1.3269/0.6636 = 2

The empirical formula would be SnO2.

What is an experimental control
attashe74 [19]

The experimental control is the standard used as a comparison for the experimental groups.


For example, you may be trying to find out how different types of disinfectants affect bacterial growth.  The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.


Hope this makes sense!
