QUESTION:
Tin (\(\mathrm{Sn}\)) exists in Earth's crust as \(\mathrm{SnO}_{2}\). Calculate the percent composition by mass of \(\mathrm{Sn}\) and \(\mathrm{O}\) in \(\mathrm{SnO}_{2}\).
ANSWER:Step 1 of 2
Here, we are going to calculate the percent composition by mass of Sn and O in \(SnO_2\).
The percent composition by mass is defined as the percent by mass of each element in a molecule.
The percent composition by mass can be calculated by using the following formula.
% composition of an element = 100%
Where n is the whole number of atoms present in the molecule.
