what is the percentage by mass of the solution formed when 22.0 grams of hcl is dissolved in 90.0 grams of water?

24.4%
22.48%
19.6%
16.7%

The equation to find the percentage by mass of a solution is:

(Mass of solute/mass of solution) x 100 = percentage by mass

So, let's identify the variables.

Mass of solute: 22g

Mass of solution: 112g

The reason that the solution is 112g and not 90g is because the solution needs to include the mass of the solute and solvent, meaning 90 + 22 is the mass of the solution.

(22/112) x 100 = 19.6%

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
