Question

If 30g of common salt dissolves in 100g of water, what is the mass of the salt solution formed?

Answer 1

I hope you understand

Answer 2

Mass of the common salt (solute) = 30 g

Mass of water ( solvent)                 = 100 g

Mass of the salt solution = ?

Mass of the salt solution = Mass of the common salt (solute) + Mass of water ( solvent)

                                        = 30 + 100 g

                                        = 130 g

Mass of salt solution = 130 g
