The average adult has about 9.0 pints of blood. If 20 drops of blood is = to 1 mL. How many drops of blood does the average human contain?

Is the answer 85,1400 drops or 85,000 drops or neither? Thanks!

• Chemistry -

I figured 85,171.7 drops which would round to 8.5E4 to two significant figures (limited by the two in the 9.0). I went to Google and typed in 9 U.S. pints to mL and hit the enter button. Saved a lot of work.
