The average uranium concentration of an ore sample in arizona is 4.5 ppm (w/w). What would be the total mass of uranium in mg that could be recovered from a 15 kg sample?
Homework Answers
The formula for ppm is:
ppm = mass of uranium * 10^6 / mass of sample
Given:
ppm = 4.5
mass of sample = 15 Kg = 15000 g
use:
ppm = mass of uranium * 10^6 / mass of sample
4.5 = mass of uranium * 10^6 / 15000
mass of uranium = 0.0675 g
= 67.5 mg
Answer: 67.5 mg
