Answer:
2.17 gm Al
Explanation:
First, find the number of moles . Then multiply by the mole weight of aluminum.
# moles = 4.85 x 10^22 / 6.022 x 10^23 = .08053 moles
.0805 moles * 26.981 gm/mole = 2.173 gm
Answer:
(a) pH = 1.0
(b) pH = 7.0
(c) 60 mL
Explanation:
(a) At the start of the titration there's no OH⁻ species yet.
pH = -log[H⁺]
And because HCl is a strong acid
[H⁺] = [HCl] = 0.1 M
Thus
pH = -log (0.1) = 1.0
(b) In every strong base-strong acid titration, the pH at the equivalence point is 7.0.
(c) Because<em> the concentration of HCl and NaOH are the same</em>, you would need<u> 30 mL of the NaOH solution to neutralize 30 mL of the HCl solution</u>, thus the total volume is 60 mL.
Yes you add water to calcium oxide it makes calcium hydroxide
