Explanation:
here's the answer to your question
All you have to do is multiply the amount of moles by 6.02x10^23 which is Avagadro's number.
Answer:
Q1: 2. Molarity.
Q2: 2.51 x 10⁻³.
Explanation:
<u><em>Q1:</em></u>
- The molarity is defined as the no. of moles of solute in one liter of solution.
- It is can be calculated from the relation: M = (no. of moles of solute)/(Volume in L of the solution).
<u><em>Q2:</em></u>
∵ pH = - log[H₃O⁺]
∴ 2.60 = - log[H₃O⁺]
log[H₃O⁺] = -2.6.
<em>∴ [H₃O⁺] = 2.51 x 10⁻³.</em>
