How many moles are in 50.18 g of CaCO3
To calculate the number of moles in 50.18 g of CaCO3, we first need to determine the molar mass of CaCO3.
The molar mass of CaCO3 can be calculated by adding the atomic masses of the individual elements:
Ca = 40.08 g/mol
C = 12.01 g/mol
O = 16.00 g/mol (3 atoms)
Molar mass of CaCO3 = 40.08 + 12.01 + (16.00 x 3) = 100.08 g/mol
Now we can calculate the number of moles in 50.18 g of CaCO3 using the formula:
Number of moles = Mass / Molar mass
Number of moles = 50.18 g / 100.08 g/mol
Number of moles = 0.5018 moles
Therefore, there are 0.5018 moles in 50.18 g of CaCO3.
