Answer:
The (H30+) is 4,13x10-8
Explanation:
We use the formula
Kwater = (H30 +) x (OH-)
1.00e-14 = (H30 +) x 2.42e-7
(H30 +) = 1.00e-14 / 2.42e-7 = 4.13e-8M

Meteorites discovered on earth
Answer:
1.26x10^25 atoms of hydrogen
Explanation:
because there are 12 atoms of hydrogen in a molecule of glucose, multiply 12 by Avogadro's number (6.02x10^23) to get how many molecules of hydrogen there are in a mole of glucose. Then multiply that number by 1.75, which is the number of moles of glucose there is in this problem.
