HONORS CHEMISTRY – Hey guys, here’s a pic of high density koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!).
So do you feel comfortable with the derived units/formulas that we discussed? Here’s the lecture from Friday. Be sure and practice the density problems and let me know Monday how you’re doing with them.
On a more practical side, how is your balance coming? Have you figured out how density plays a major part in how it works? Here are the actual masses. Are your answers close to these? If not, what could be some reasons? Make sure you include that in your conclusion. Holler if you have any questions! 🙂
• Penny: 3.1 g before 1982, 2.5 g after
• Nickel: 4.95 g
• Dime: 2.25 g
• New state quarter: 5.68 g
Why have scientists not found a non-physical standard for mass?
Those coi fish are packed really tight! Looks uncomfortable…

How many decimal places do we need to round to?
Andrea – Funny you should mention that! We are going to talk about it Monday. For now, just rounding to a couple of places will be okay.
Thanks for putting the actual masses on here! It helped me make sure I did it correctly.
Marti – You’re welcome! 🙂
