Moles from ml and m

  • To find out how many moles of salt are contained in 300. ml of a 0.40 M NaCl solution, we start with the volume in liters (0.300 L) and multiply it by the number ofmoles per liter of solution, which is 0.40moles over 1.00 L. The answer is 0.12moles of NaCl.

    The mole may also be used to measure the amount of atoms, ions, electrons, or other entities. The concentration of a solution is commonly expressed by its molarity, defined as the amount of dissolved substance in mole(s) per unit volume of solution, for which the unit typically used is moles per litre (mol/l), commonly abbreviated M.

The volume 250 ml is equal to 0 .250 L. Now substituting these values in the above equation yields the molarity of the solution. To solve for moles of KNO3, you need to convert the volume into liters (50 ml = 0.050 L), and substitute in the molarity equation.
