How do you create a 1 M solution from 25 grams of Na2CO3 A 1

How do you create a 1 M solution from 2.5 grams of Na2CO3? A 1 M solution from 2.5 grams of NaHCO3?

Solution

Na2CO3 molecular weight is 106 gm

NO of moles = 2.5/106 = 0.0236 Moles

Molarity = Moles/Volume

1 = 0.0236 / Volume

Volume = 0.0236 Litres = 23.6 mL

Therefore, by dissolving 2.5 gms Na2CO3 in 23.6 mL of water.

NaHCO3 molecular weight is 84 gm

NO of moles = 2.5/84 = 0.0298 Moles

Molarity = Moles/Volume

1 = 0.0298 / Volume

Volume = 0.0298 Litres = 29.8 mL

Therefore, by dissolving 2.5 gms Na2CO3 in 29.8 mL of water.
