The concentration of each solution will be given in molarity (M). Molarity is a quantity that expresses the moles of solute present per liter of solution. A sodium hydroxide solution is labeled as 0.1020 M. i. Write that as a ratio of moles and liters. ii. If 11.25 mL of the 0.1020 M NaOH solution is used to titrate a solution, then how many moles of NaOH does that represent? iii. If the number of moles of unknown acid neutralized are determined to...

D 6. A solution of KOH has a Molarity of 1.5. How many liters of this solution would contain 3.0 moles of KOH? 0.22 L 4.5 L 2.0 L 3.0 L 0.50 L
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...

Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20∘C. A 2.500×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by...
