In 70 g of water, 30 g of salt was dissolved. What is the concentration of the resulting solution?

The concentration of a substance in a solution is the ratio of the mass of a substance to the total mass of a solution. In our case, the mass of salt = 30 g, the mass of the solution = 30 (g of salt) + 70 (g of water) = 100 g.

Let’s calculate the percentage of salt concentration in the resulting solution: 30/100 * 100% = 30%
