You have gone into the field to take water samples from
two lakes in your town.
You note the following observations:
Think about how acids and bases would affect the
water quality in the two lakes.
Which set of pH data would you expect to see based
on your observations?
Lake A contained many fish swimming in its waters.
Lake B had very few fish swimming in its waters,
and a few dead fish floating on the water.
Lake A: pH = 4.5; Lake B: pH = 7.5
Lake A pH = 8.3, Lake B: pH = 3.7
Lake A: pH = 6.6, Lake B: pH = 6.8
Lake A pH = 10.2; Lake B: pH = 1.7
You return to your lab and take pH readings for each
sample

Lake A: pH = 8.3; Lake B: pH = 3.7

Explanation:

That is the answer on edg <3

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
