Q #13 How many moles of MgCl2 are there in 350. g of compound?

Answer 1

3.67 moles

Explanation:

We need to find out the number of
`MgCl_2` moles present in 350 grams of a compound.

Molar mass of
`Mg` = 24.305

Molar mass of
`Cl_2` = 35.453

So, one mole of
`MgCl_2` = 24.305 + (35.453 * 2) = 95.211g

1 Mole in 1 molecule of
`MgCl_2` =
`(1)/(95.211) = 0.0105`

Therefore, number of moles in 350 grams of compound = 0.0105 * 350

= 3.67 moles
