The Importance of Calculating the Amount of Water Necessary to Make a Solution of a Solute

The importance of accurately calculating the amount of water necessary to make a solution of a solute cannot be overstated. Knowing the amount of water necessary to make a solution of a solute is fundamental to a variety of disciplines, including chemistry and biology (Coulson et al., 2015). For example, if one wishes to make a 500 ppm solution of sodium chloride (NaCl), one must first calculate the amount of water needed to achieve the desired concentration. To calculate the amount of water necessary to make a 500 ppm solution of NaCl, one must first determine the mass of the solute. In this example, the mass of the solute is 0.200 g (Cooper et al., 2018). Once the mass of the solute is determined, one can then calculate the amount of water necessary to make the solution. To do this, the mass of the solute is multiplied by 10, which yields a value of 2 g (Coulson et al., 2015). Thus, the amount of water needed to make a 500 ppm solution of NaCl is 2 g – 0.200 g = 1.800 g. Cont…
