2. The Food and Drug Administration (FDA) mandates that all vinegar sold in the United States must have a minimum concentration
Scilla [17]

Answer:

The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.

Explanation:

4% acetic acid by mass means that 4 gram of acetic acid in 100 g solution.

Given that density of the vinegar is same is that of water =  1 g/mL

Mass of the vinegar solution = 100 g

Volume of the vinegar solution = V

Density=\frac{Mass}{Volume}

1 g/mL=\frac{100 g}{V}

V = 100 mL = 0.1 L

Moles of acetic acid =\frac{4 g}{60.052 g/mol}=0.0666 mol

Molarity=\frac{\text{Moles of solute}}{\text{Volume of solution(L)}}

M=\frac{0.0666 mol}{0.1 L}=0.6660 mol/L

The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.

What is the pH of the solution if the [H+] is 1 x 10-12 ?
jarptica [38.1K]

Answer:

<h2>12</h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

From the question we have

pH =  -  log(1 \times  {10}^{ - 12} )  \\

We have the final answer as

<h3>12</h3>

What happens to the population growth in a logistic growth pattern as it approaches carrying capacity?
AveGali [126]
B. slows down is your answer, obviously as it approaches carrying capacity, there would be less available space to find in the place of inhabitance, so less and less population units would be able to find the place of inhabitance suitable for living, or can't find enough space to live in.
