I need help figuring out the ppm$!!!!!!!!!!!!!!!!$A $5mL$ aliquot of the $0\mathrm{.}02196M$ "stock" solution is transferred to a fresh $100mL$ volumetric flask and filled to the etched line.

What is the concentration of calcium nitrate in this diluted solution in molarity? Include the unit.

concentration $=$

What is the concentration of the diluted solution in ppm $($you can assume the density of the solution is $1\mathrm{.}00\frac{g}{m}L)?$

concentration $=$
