Question

What is the mass in grams of 1.73 mol Cal2

Answer 1

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

Answer 2

Step-by-step explanation:

It is known that number of moles equal mass divided by molar mass.

Mathematically, No. of moles =
`\frac{mass}{\text{molar mass}}`

It is known that molar mass of
`CaI_(2)` is 293.887 g/mol and number of moles given are 1.73 mol.

Hence, calculate the mass as follows.

No. of moles =
`\frac{mass}{\text{molar mass}}`

1.73 mol =
`(mass)/(293.887 g/mol)`

mass = 508.424 g

Thus, we can conclude that mass of
`CaI_(2)` is 508.424 g.
