Answer :
The Number of Moles of Zn is 0.34108 and the number of moles of Cr2O3 is 0.14671.
What is Number of Moles?
The ratio of a substance's given mass in a chemical reaction to the mass of one mole of that material is what determines how many moles there are of that substance. A mole of any substance is equal to 6.0231023, or Avogadro's number. The ratio of a substance's given mass in any kind of chemical reaction to the mass of one mole of that material is the number of moles of that substance.
Moles of Zn can be calculated by using the formula
22.3 g of Zn x 1 mole Zn/65.4 g = 0.341 moles of Zn.
Moles of Cr2O3 can be calculated by using the formula
22.3 g of Cr2O3 x 1 mole Cr2O3/151.99 = 0.146 moles of Cr2O3.
Hence, 0.34108 and 0.14671 will be the number of moles for Zn adn Cr2O3 respectively.

Zn has a mole count of 0.34108, while Cr2O3 has a mole count of 0.14671.
What is Number of Moles?
The number of moles of a substance is determined by the ratio of its given mass in a chemical reaction towards the mass of one mole of that substance. A mole, or 6.0231023, is equal to one mole of any substance. The number of moles of a substance is defined as the mass of one mole divided by the given mass of the substance in any type of chemical reaction.
The formula can be used to determine moles of zinc.
22.3 g of Zn x 1 mole Zn/65.4 g = 0.341 moles of Zn.
The formula can be used to determine moles of Cr2O3.
22.3 g of Cr2O3 x 1 mole Cr2O3/151.99 = 0.146 moles of Cr2O3.
Therefore, the moles of Zn and Cr2O3 will be 0.34108 and 0.14671, respectively.
