  • So to determine molar mass, we need to look at the periodic table. The periodic table says that a mole of zinc weighs 65.38 grams (atomic mass gives you that number). It also says that a mole of chlorine weighs 35.45 grams. Well in the formula for ZnCl2 we can see that there are two chlorines. So to figure out total mass we will do 65.38+(2)(35.45). That gives us the total mass which is 136.28
  • The molar mass of glucose, (C6H12O6) is 180.2 g and the density of the solution is 1.16 g/mL. Try this: Calculate the molarity of a 1.74 m sucrose (C 12 H 22 O 11 ) solution whose density is 1.12 g/mL.
  • Now, you know that the mass of this sample will be equal to the mass of the ethanol, the solute, and the mass of the water, the solvent. m_ "solution" = m_ "ethanol" + m_ "water" In your case, you will have m_ "ethanol" + m_ "water" = "100 g" " "color(darkorange)((1)) You also know that the mole fraction of ethanol, which is defined as the ratio between the number of moles of ethanol and the
  • The molar mass of benzene (C6H6) is 78.11 grams per mole. The molarmass of toluene is 92.14 grams per mole. Mole fraction of a soluteequals moles of solute divided by the mole The molarmass of toluene is 92.14 grams per mole.
