A KNO3 solution is made using 88.4g of KNO3 and diluting to a total soultion volume of 1.50l. Calculate the molarity and mass percent of the solution. Assume a density of 1.05 g/mL for the solution.

  • chemistry -

    88.4 g KNO3 = ? moles. moles = grams/molar mass = 88.4/molar mass KNO3 = about 0.88 moles. In a total volume fo 1.50 L, that will be 0.88/1.5 = ?M.

    For mass percent, that is mass/100 g sample.
    (88.4/mass soln)*100 = ?
    Convert 1.50L volume to mass using density, ans substitute in the mass percent equation, solve for mass percent.
