For instance, if a store offers a 10% discount on an item priced at $500, the discount amount would be 10% of $500, which is $50. Thus, the sale price of the item would be $500 – $50 = $450.
10 percent solution means the solute is only 10% in the solution, so taking the volume of the solvent 100 ml then the mass of the solute will be either 10 gram or 10 ml. For example, 10% solution of sodium chloride ($NaCl$) means 10 grams of sodium chloride is mixed in 100 ml of water.
Example: 10 mL of ethyl alcohol plus 90 mL of H2O (making approx. 100 mL of solution) is a 10% by volume solution. Mass-volume percent solutions are also very common. These solutions are indicated by w/v% and are defined as the grams of solute per 100 milliliters of solution.
While 10 percent of any amount is the amount multiplied by 0.1, an easier way to calculate 10 percent is to divide the amount by 10. So, 10 percent of $18.40, divided by 10, equates to $1.84.
