Question

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

Answer 1

Answer:

203.752 grams

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:

$1\ mol=95.211\ g\\2.14\ mol=X\\\\\#Cross \ multiply\\\\X=\frac{2.14\ mol\times 95.211\ g}{1\ mol}\\\\=203.752\ g$

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