Answer:
693000
Explanation:
Multiplying anything by 10 must follow the base 10 system rules.
That means we can simply move the decimal 5 places to the right.
6.93 x 10⁵ = 693000
Answer:
[OH-] = 1.08x10^-11 M
Explanation:
From the question given,
Concentration of Hydrogen ion, [H+]
= 9.3x10^-4 M
Concentration of Hydroxide ion, [OH-] =..?
The concentration of the hydrogen ion, [H+] and hydroxide ion, [OH-] are related with the following formula:
[H+] x [OH-] = 1x10^-14
Using the above formula, we can easily calculate the concentration of the hydroxide ion, [OH-] as follow:
[H+] x [OH-] = 1x10^-14
[H+] = 9.3x10^-4 M
9.3x10^-4 x [OH-] = 1x10^-14
Divide both side by 9.3x10^-4
[OH-] = 1x10^-14 /9.3x10^-4
[OH-] = 1.08x10^-11 M
