To calculate the number of moles in SnO2, we need to know the molar mass of SnO2.

The molar mass of SnO2 is calculated by adding up the atomic masses of each element in the compound.

The atomic mass of Sn (tin) is 118.71 g/mol, and the atomic mass of O (oxygen) is 16.00 g/mol.

So, the molar mass of SnO2 is:

(1 * 118.71 g/mol) + (2 * 16.00 g/mol) = 118.71 g/mol + 32.00 g/mol = 150.71 g/mol

To find the number of moles, we can use the formula:

moles = mass / molar mass

moles = 3.20 g / 150.71 g/mol = 0.0213 mol

Therefore, there are approximately 0.0213 moles in 3.20 g of SnO2.
