Nutrition experts recommend that you drink at least 8 cups of water daily. If your local water supply contains 1.00 part fluoride (by mass) per millions part water, how many milligrams of fluoride would you consume daily in your 8 cups of water? (use 1.00 g/cm^3 as the density of water).
what is the similarity between metal olefin and metal hydrogen
Observe significant figure rules. Constants: ideal gas const = R = 0.08206 L atm/mole K; 1 mole of gas at STP occupies 22.41 L. Atomic masses: H 1.008 O 16.000 g/mole. You must show work to identify the limiting reagent; no credit for guessing.
