Question

How many grams of MgCl2 are in 2.14 moles of MgCl2?

Answer 1

203.752 grams

Step-by-step explanation:

-The molar mass of
`MgCl_2` is 95.211 g/mol

-Let X be the mass of
`MgCl_2` in grams.

-Given 2.14 moles of
`MgCl_2`, we convert into grams as follows:

`1\ mol=95.211\ g\\2.14\ mol=X\\\\\#Cross \ multiply\\\\X=(2.14\ mol* 95.211\ g)/(1\ mol)\\\\=203.752\ g`

Hence, there are 203.752 grams of
`MgCl_2` in 2.14moles of MgCl2
