Blood sample question
« on: September 16, 2009, 02:31:31 PM »
A blood sample is found to contain 8.6 mg/dL of Ca. How many atoms of Ca are present in 8.6 mg? The Atomic weight of Ca is 40.08. How would I set up a math problem to solve this? Thanks!

Calculate the number of moles then multiply by avagadros number.
