Explanation:
I thought it was B, but i was wrong... TwT, so now you know not to choose that one, but i belive the right answer was D.
The molarity of a Ba(OH)2 solution required to prepare a1.0 OH- solution is calculated as follows
write the equation for dissociation of Ba(Oh)2
that is,
Ba(Oh)2 -----> Ba^2+ + 2Oh-
by use of reacting ratio between Ba(Oh)2 to Oh which is 1:2 the molarity of Ba(oh)2 = 1.0/2 = 0.5 M
After 3 half lives it will be (1/2)^3 or 1/8 of original
so
1/8 times 10^8=1.25 x 10⁶ atoms left
