Answer:
3.67 moles
Step-by-step explanation:
We need to find out the number of [tex]MgCl_2[/tex] moles present in 350 grams of a compound.
Molar mass of [tex]Mg[/tex] = 24.305
Molar mass of [tex]Cl_2[/tex] = 35.453
So, one mole of [tex]MgCl_2[/tex] = 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of [tex]MgCl_2[/tex] = [tex]\frac{1}{95.211} = 0.0105[/tex]
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
