Answer:
5.01 moles
Explanation:
Calculate the number of moles in 400g of Tio2
first, write the formulas correctly
Calculate the number of moles in 400g of TiO2
capitalize the first letter of your elements
the molar mass of TiO2 is
47.88 +2X16.00 =47.88 +32.00 = 79.88 gm/mole
(to 3 sig fig = 79.9 gm/mole
400 gm/79.9 gm/mole = 400/79.9 mole gm/gm =
400/79.9 moles = 5.01 moles
