Kool-Aid dye in solution calculations

data:

allura red ac: molar absorptivity (L/ (mol*cm)) = 2.41 * 105 ; analytical wavelength (nm)= 505; molecular weight(g/mol)= 496.42

ratio of dye in solution c to solution a: 0.1
amount of koolaid added= 0.485g

1) calculate the concentration of the dye in solution in in units of moles per liter kool aid solution
2) calculate the mass of the dye per liter koolaid solution c in units of grams/L
3) calculate the ppm concentration of the dye in koolaid solution c on a mass to volume basis.

if any other information is needed please leave a comment.
