The number of formula units of CaCo₃ that are present in 4.72 moles calcium carbonate is 2.841 x 10²⁴
calculation
The number of formula units is calculated using the Avogadro's constant
That is according to Avogadro's law
1 mole = 6.02 x 10²³ formula units
4.72 moles=? formula units
by cross multiplication
=[ (4.72 moles x 6.02 x 10²³ formula units) / 1 mole = 2.841 x 10²⁴ formula units
