Question

calculate molarity and normality of 9.8g h²so⁴ in 250ml water​

Answer 1

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
