Question

How many moles of Na2O are in 350 mL of 1.2 M solution?

Answer 1

0.42 moles Na₂O

Step-by-step explanation:

Molarity: 1.2 M

Volume (mL): 350 mL

Volume (L): 0.35 L

350 mL / 1,000 mL = 0.35 L Na₂O

Molarity (M) = moles / liters (L)

1.2 M Na₂O = ? moles / 0.35 L Na₂O

(1.2 M Na₂O) x (0.35 L Na₂O) = ? moles

? = 0.42 moles Na₂O
