Unit Conversion question
« on: January 14, 2006, 11:14:45 AM »

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?"

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!
