If 1.06mmole of 1-pentanol and 1.53mmole of 1-Hexanol were separated by gas chromotography, they gave relative peak areas of 922 and 1570 units, respectively. When an unknown mixture of these two alcohols was likewise separated, the relative peak areas were 843:816 (pentanol:hexanol). What was the relative concentration of these species in the mixture?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
