Answer:
The answer to your question is 0.04 M
Explanation:
Data
mass of Na₂SO₄ = 14.2 g
volume = 2.50 l
Molarity = ?
Process
1.- Calculate the molar mass of Na₂SO₄
Na₂SO₄ = (23 x 2) + (32 x 1) + (16 x 4) = 46 + 32 + 64 = 142 g
2.- Calculate the number of moles of Na₂SO₄
142 g of Na₂SO₄ ------------------- 1 mol
14.2 g of Na₂SO₄ ------------------ x
x = (14.2 x 1) / 142
x = 0.1 moles
3.- Calculate the molarity
Molarity = moles /volume
-Substitution
Molarity = 0.1 / 2.5
-Result
Molarity = 0.04
