Unit Conversion question
« on: January 14, 2006, 05:14:45 PM »
I don't understand where to start on this question Can someone help?

The Acidic constituent in vinegar is acetic acid. A 10.0mL sample of a certain vinegar contains 483mg of acetic acid. What is the mass of acetic acid expressed in micrograms.

I know that the SI prefixes for micro is 10^-6 but how do I start this?

If you had 1 milligram how many micrograms would be in it? Its the same answer if you ask, "if you have a $1000 vill how many single $1 do you have?"
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

If you're uncomfortable with converting directly from milligrams to micrograms, try converting to grams first.  How many milligrams are there in a gram?  Work that out first.  Then, since you know that micro- means x10-6, you can easily convert from grams to micrograms!
