Answer:
24 pills
Explanation:
650 mg/1000 = 0.65 g
(There are 1000 mg in one g)
15.6g/0.65g=24
Answer:
pH = 5.06, solution is acidic
Explanation:
pH = - log [H+]
we are given, [H+] as 8.7 x 10^-6M
Therefore;
pH = - log (8.7 x 10^-6 M)
= 5.06
pH = 5.06
But a solution with a pH of, 1-6 is acidic, while a pH of 7 is neutral and that of 8-14 is basic.
Thus; a pH of 5.06 is acidic
