Thirty grams of lye was dissolved in enough water to make 1L of solution how many grams of lye would be in 75ml of the solution? Scribes the concentration of a solution in moles of solute divided by liters of solution. Masses of solute must first be converted to moles using the molar mass of the solute. This is the most widely used unit for concentration when preparing solutions in chemistry and biology. The units of molarity, mol/L, are usually represented by a scripted capital "M". Calculate the concentration, in moles of solute per liter of solution, of each of the following: Example: 10 grams of NaOH is dissolved in enough water to make 2 L of solution Step #1 - Convert grams of solute to moles of solute: 10 g NaOH 1mol NaOH = 0.250 mol NaOH 40 g NaOH Step #2 – Divide moles of solute by liters of solution: 0.250 mol NaOH = 0.125 M NaOH 2L 1) 20 grams of NaOH is dissolved in enough water to make 1 liter of solution 2) 45 grams of glucose, C6H12O6 is dissolve
