Tricky!1 liter of an aqueous solution contains 6.02 X 10^21 H3O ions.Therefore its H3O ion concentration is.?
b. 0.100 mole per liter
c. 1.00 mole per liter
d. 6.02 X 10^ 21 mole per liter
e. 6.02 X 10^ 23 mole per liter.
Help!!
Answer:
The answer is A
6.02E21 / 6.02E23 = 0.01 mole/ liter
where 6.02x10^23 is Avogadro's number (the number of molecules in a mole)
Good luck!
I think I'm missing the tricky part:
6.02 x 10^21 (1 mol/6.022 x 10^23) = 0.0100 mol
Divide by 1 L and you will get 0.0100 M
