A. 4.5mg

B. 270mg

C. 2.7grams

D. None of the above

Please include the equation?

Thank you!

Jim, I'm answering this on my phone from a Starbucks hot-spot, so I didn't write it down. Hope it's correct. Here's what I think:

600 drops in 1/Hour

----------------------------

60 drops per/mL

= 10mL/Hour

450mg - - - 4.5mg

------- = --------

1000ml - - - 10ml
