I'm pretty sure that you multiply the number of moles by avogadro's number (6.02x10^23)... you may want to check.
There are 84 metal elements
According to Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺).
1) NH₄⁺(aq) + H₂O(l) ⇄ NH₃ + H₃O⁺(aq); the ammonium cation (NH₄⁺) gives proton to water.
2) [Co(H₂O)₆]³⁺ + H₂O ⇌ [Co(H₂O)₅(OH)]²⁺ + H₃O⁺; cobalt cation (Co³⁺) forms complex cation with six molecules of water, which act like acid and gives protons.
3) CH₂NH₃⁺(aq) + H₂O(l) ⇄ CH₂NH₂ + H₃O⁺(aq); H⁺ is cationic form of atomic hydrogen, the hydrated form of the hydrogen cation is the hydronium ion H₃O⁺(aq).
Answer:
[CH₃COOH] = 17.4 M
Explanation:
Acetic acid → CH₃COOH
Molar mass → 60 g/mol
99.5% is percent by mass concentration. It means that 99.5 grams of solute are contained in 100g of solution.
Density → 1.05 g/mL. This data is always referred to solution, not solute!.
We determine solution's volume:
1.05 g/mL = 100 g / V → V = 100 g /1.05 g/mL → 95.2 mL
Now we know, that 99.5 g of acetic acid are contained in 95.2 mL
Let's convert to mmoles → 99.5 g / 60 g/mol = 1.66 moles
We convert solution's volume to L → 95.2 mL . 1L / 1000 mL = 0.0952 L
M (mol/L) = 1.66 mol / 0.0952 L = 17.4 M
