Question

11) How many grams are in 2.3 moles of magnesium chloride, MgCl,?

Answer 1

218.98 grams

Step-by-step explanation:

Given that,

No. of moles, n = 2.3

The molar mass of magnesium chloride is 95.211 g/mol.

We need to find the mass of 2.3 moles of magnesium chloride.

We know that,

No. of moles = given mass/molar mass

Let m be the given mass. So,

`m=n* M\\\\=2.3* 95.211 \\\\=218.98\ g`

So, the required mass is equal to 218.98 grams.
