Question

@aaronq conversion from concentration to micrograms/mL

Answer 1

concentration in what units?

Answer 2

molarity

Answer 3

\(\sf Molarity=\dfrac{moles}{L}=\dfrac{mass}{Molar~mass*L}\)


so, \(\sf\dfrac{mass}{L}=Molarity*Molar~mass\)

then it's just a conversion between grams to micrograms

\(\sf 1\mu g=1*10^{-6}g\)

Answer 4

@aaronq whats molar mass of iron

Answer 5

55.85 g/mol

you can always just google these

Answer 6

my concentration is 1.002816901 so times it by 55.85

Answer 7

yep

Answer 8

then divided it by 1*10^-6

Answer 9

yes, then convert /L to /mL

Answer 10

@aaronq i got 56007, the concentration should be below 1

Answer 11

@aaronq move decimal place 6 places left

Answer 12

oh wait you're supposed to multiply not divide

Answer 13

@aaronq whats ur email address. But, it should be below 1

Answer 14

\(\dfrac{g}{L}*\dfrac{1*10^{-6}\mu g}{g}*\dfrac{L}{1000~mL}\)
