How many moles are in 4.80 grams on SnO2?
4.80 g/molar mass SnO2.
Calculate the number of moles of 4.80g Al.
To determine the number of moles in 4.80 grams of SnO2, you need to use the concept of molar mass and the formula:
moles = mass (in grams) / molar mass
First, you need to find the molar mass of SnO2. It is calculated by adding up the atomic masses of the elements 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:
Molar mass = (1 x Sn's atomic mass) + (2 x O's atomic mass)
= (1 x 118.71) + (2 x 16.00)
= 118.71 + 32.00
= 150.71 g/mol
Now that you have the molar mass, you can calculate the number of moles:
moles = mass (in grams) / molar mass
= 4.80 g / 150.71 g/mol
By dividing 4.80 grams by 150.71 grams/mol, you will get the result in moles.
