1. Molarity (M): moles of solute/liters of solution or moles/L (mol/L) 2. w/v (g/mL): weight in grams of solute/milliliters of solute 3. w/w: weight in grams of solute/weight in grams of solution (g/g) 4. v/v: volume of solute/volume of solution (L/L) Molar Mass ...
Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...

What is the molarity of a solution when you have 2 moles of ammonium chloride (AgNO3) in 1 L? What is the final volume after diluting 50.0 mL of a 12.0 M NH4Cl solution to give a 2.00 M NH4Cl solution? given two separate solutions, .1 M ammo...
What is the molarity of the solution? How to make up 300 mL of a 0.9 percent NaCl solution? Calculate the molarity of a 325 mL that contains 6.7 g NaCl. Calculate the volume (in L) of a solution that contains 3.12 moles of NaCl if the concentration of this solution ...
Calculate the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of a 0.800 M NaOH solution. Calculate the molarity of HCl and NaOH. Given: HCl volume = 25 mL NaOH = 67.05 mL moles of NaOH = 0.015000 moles ...
