Question

Given a 1.50 Liters of solution that contains 62.5 grams of magnesium oxide. What is the Molarity of that solution?

Answer 1

RMM of magnesium oxide=24+16=40
40g=1mol
therefore 62.5g will have =62.5/40=1.5625 moles
1.5 litres contain 1.5625 mols
therefore 1 litre =1*1.5625/1.5=1.042M

Answer 2

Answer:

1.5507

Explanation:

First convert the the magnesium oxide from 62.5G ——-> 1.55069918moles

Now we use the formula

Moles/liters =Molarity

1.55069918m/1.50L =1.55069918mole
