Question

The 100 cm³ of a solution is obtained by dissolving 5.85g of nacl in eater the molarity if solution would be

Answer 1

Answer: 1 M

Explanation:

Volume of Solution= 100 cm³= 0.1 dm³

Mass of Solute = 5.85 g

Molar mass of solute = 23+35.5 = 58.5 g/mol

Molarity of solution = Mass of solute/Molar mass of Solute   X   1/Vol. of solution in dm³

Molarity = 5.85/58.5    X    1/0.1 dm³

Molarity = 0.1 x 1/0.1

Molarity = 1 M (Ans)
