Express the concentration of a 0.0220 M aqueous solution of fluoride, F-, in mass percentage and in parts per million. Assume the density of the solution is 1.00g/mL.

Solution

molarity=0.022 M

so,

mass in 1 liter water=0.022*19

=0.418 g

mass of water=1000g

so mass %=0.418*100/(1000+0.418)

=0.0418 %.

b)in ppm=418.477 ppm
