Answer:
Yes
Explanation:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what is meant by "thin air".
Answer:
605.6mg of quinine
Explanation:
Based on Lambert-Beer's law, the intensity of an optical measurement is directely proportional to its concentration.
Unknown concentration gives a reading of 327
100 ppm gives 180 of intensity
The concentration of the diluted quinine tablet is:
327 * (100ppm / 180) = 181.67 ppm. The final dilution
The concentration of the first diluted solution is:
181.67 ppm * (100.0mL / 15mL) = 1211ppm
ppm could be defined as mass of solute (In this case of quinine) in mg per liter of solution. That is:
1211mg / L
As the tablet was diluted to 500mL = 0.5L, the mass of the quinine is:
0.5L * (1211mg / L) =
<h3>605.6mg of quinine </h3>
A solid, a liquid or a gas.
Answer:The Old Sow whirlpool is located off the southwestern shore of Deer Island, New Brunswick between the island and Eastport, Maine. The whirlpool is caused by variations in local bathymetry combined with the extreme tidal range of the Western Passage where waters exchange between Passamaquoddy Bay and the Bay of Fundy.
