Question

How many moles of mgci2 are there in 326 g of the compound

Answer 1

Hello!

The answer is: There are 3.42 moles of MgCl2 in 326g of the compound.

Why?

Assuming that the compound is MgCl2, we can find how many moles of the compound are in 326 g of the same compound, calculating the molar mass of the compound, so:

$Mg=24.305\frac{g}{mol}\\\\Cl=35.45\frac{g}{mol}$

Then,

$MgCl2MolarMass=24.305+(2*35.45)=95.21\frac{g}{mol}$

Therefore, to calculate how many moles are in 326 of the compound, we can use the following equation

$Moles=\frac{mass}{molarmass} =\frac{326g}{95.21\frac{g}{mol}}=3.42molesMgCl2$

Hence,

There are 3.42 moles of MgCl2 in 326g of the compound.

Have a nice day!
