Answer: 0.30 M
Explanation:

According to the neutralization law,
where,
= molarity of
solution = ?
= volume of
solution = 24.6 ml
= molarity of
solution = 0.222 M
= volume of
solution = 33.0 ml
= valency of
= 21
= valency of
= 1
Therefore, the molarity of the HCI solution is 0.30 M
D. 2.2 pounds would be the answer
Answer:
pH = 12.544
Explanation:
0.0350M 0.0350M 0.0350M.........equilibrium
∴ pOH = - log [OH-]
∴ pH + pOH = 14
⇒ [OH-] = 0.0350 M
⇒ pOH = - Log (0.0350)
⇒ pOH = 1.456
⇒ pH = 14 - 1.456
⇒ pH = 12.544
The sum of the number of protons and neutrons in the nucleus of an atom is called the mass number (A), or nucleon number.
