Answer:
if you meant moles this is the answer 1
mol of lithium bromide has a mass of
86.85g⋅mol−1. You have 2.6 moles
Explanation: mass = 86.85g⋅ mol−1× 2.6 mol
calcium,phosphorus,potassium,and sulfer
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
A buffer solution is a aqueous solution consisting of a mixture of a weak acid and it conjugate base, or vice versa.
