Calculate the molarity of a solution containing 9.8 gm of H SO.250cm3

1.	Calculate the molarity of a solution containing 9.8 gm of H SO.250cm3 of aqueous solution.
Answer» Moles of solute = Mass of solute / Molar mass of solute= 9.8 g / 98 g/mol= 0.1 mol Volume of solution = 25 cm³ = 0.025 Litres Molarity = Moles of solutes / Volume of solution in litres= 0.1 mol / 0.025 litres= 4 M Molarity of given solution is 4 M

Calculate the molarity of a solution containing 9.8 gm of H SO.250cm3 of aqueous solution.

Answer»

Moles of solute = Mass of solute / Molar mass of solute= 9.8 g / 98 g/mol= 0.1 mol

Volume of solution = 25 cm³ = 0.025 Litres

Molarity = Moles of solutes / Volume of solution in litres= 0.1 mol / 0.025 litres= 4 M

Molarity of given solution is 4 M
