I am having major trouble trying to figure the concentration of a substance that is given by the AAS. Here's the question:
To determine the iron content in a 'Milo' milk drink, a 5ml sample was diluted to 50ml. the absorption of the diluted solution and of several standard solution were measured using AAS.
What mass of iron would you consume by drinking 250ml glass of Milo?
It is given that the concentration of iron, in ppm, in the diluted milo is 2.57ppm hence the concentration of iron, in ppm, in the undiluted milo is 25.7ppm.
If anybody could work this out it would be greatly appreciated
Thanx:)
