How many moles of Na₂SO₄ are in a 0.140 m aqueous solution that was prepared with 2.30 kg of water?
The solution is 0.140 m. Hence, 1 kg (1000 g ) of water (solvent) contains 0.140 moles of sodium sulphate (solute). The conversion factor is .
Aqueous solution was prepared with 2.30 kg of water.
Hence, 0.322 moles of sodium sulphate are present in a 0.140 m aqueous solution that was prepared with 2.30 kg of water.
