Concentration is the amount of solute dissolved in a certain amount of solution: Solution concentrations are usually given as one of the following: ● Mass percent (m/m)-the mass of the solute in grams for exactly 100 g of solution • Volume percent (v/v)-the volume of solute in exactly 100 mL of solution • Mass/volume percent (m/v)-the mass of solute in grams for exactly 100 mL of solution ● Molarity (M)-the number of moles of solute in exactly 1 L of solution Part A Calculate the mass percent (m/m) of a solution prepared by dissolving 43.37 g of NaCl in 171.3 g of H₂O. Express your answer to four significant figures. ► View Available Hint(s) Mass percent (m/m) = concentration of a solution = _amount of solute amount of solution Submit Π| ΑΣΦ ? % P Pearson Copyright © 2023 Pearson Education Inc.
