First you find the molar mass of the compound.
1Ca: 40.078g/mol
2I: 126.904g/mol
CaI₂:293.886g/mol
Now you multiply the mols by the molar mass:
1.73mol CaI₂ₓ 293.886g/1mol ≈ 508g CaI₂
Explanation:
It is known that number of moles equal mass divided by molar mass.
Mathematically, No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
It is known that molar mass of [tex]CaI_{2}[/tex] is 293.887 g/mol and number of moles given are 1.73 mol.
Hence, calculate the mass as follows.
No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
1.73 mol = [tex]\frac{mass}{293.887 g/mol}[/tex]
mass = 508.424 g
Thus, we can conclude that mass of [tex]CaI_{2}[/tex] is 508.424 g.
