A sample of vinegar has a hydronium concentration of 1.6 × 10-3 M. What is the pH of the vinegar?
loris [4]
PH is defined as the negative log of Hydronium Ion concentration.

So, in order to find the pH of vinegar, we find the negative log of its hydronium ion concentration.

pH=-log[ H_{3}O^{+}] \\  \\ 
pH=-log(1.6  * 10^{-3})  \\  \\ 
pH=2.8

So, the pH of given vinegar solution will be 2.8.

Therefore, the answer to this question is option B

1.For the reaction P4 O10(s) + 6H2O(l) → 4H3PO4(aq), what mass of P
Alex17521 [72]
P₄O₁₀ + 6H₂O → 4H₃PO₄
The equation shows us that the molar ratio of
P₄O₁₀ : 6H₂O = 1:6

We also know that one mole of a substance contains 6.02 x 10²³ particles. We can use this to calculate the moles of water.
moles(H₂O) = (5.51 x 10²³) / (6.02 x 10²³)
= 0.92 mole
That means moles of P₄O₁₀ = 0.92 / 6
= 0.15

Each mole of P₄O₁₀ contains 4 moles of P. 
moles(P) = 4 x 0.15 = 0.6 mol
Mr of P = 207 grams per mol
Mass of P = 207 x 0.6
= 124.2 grams
