The {{\text{H}}^+} concentration of vinegar solution is \boxed{{\text{0}}{\text{.0000708 M}}}

Further Explanation:

An acid is a substance that has the ability to donate {{\mathbf{H}}^{\mathbf{+}}}ions or can accept electrons from the electron-rich species. The general dissociation reaction of acid is as follows:

{\text{HA}}\to{{\text{H}}^+}+{{\text{A}}^-}

Here, HA is an acid.

The acidic strength of an acid can be determined by pH value. The negative logarithm of hydronium ion concentration is defined as pH of the solution. Lower the pH value of an acid, the stronger will be the acid. Acidic solutions are likely to have pH less than 7. Basic or alkaline solutions have pH more than 7. Neutral solutions have pH equal to 7.

Vinegar contains acetic acid \left({{\text{C}}{{\text{H}}_3}{\text{COOH}}}\right), water and some traces of other chemicals and flavors.

The formula to calculate pH is as follows:

{\text{pH}}=-{\text{log}}\left[{{{\text{H}}^+}}\right]                                   …… (1)

Here,

\left[{{{\text{H}}^+}}\right] is hydrogen ion concentration.

On rearranging equation (1), we get:

\left[{{{\text{H}}^+}}\right]={10^{-{\text{pH}}}}                                           …… (2)

The pH of vinegar is 4.15.

Substitute 4.15 for pH in equation (2)

\begin{gathered}\left[{{{\text{H}}^+}}\right]={10^{-4.15}}\\=0.0000707946\\\approx0.0000708\;{\text{M}}\\\end{gathered}

So the concentration of {{\mathbf{H}}^{\mathbf{+}}} ion in vinegar is 0.0000708 M.

<span>The pH of a vinegar solution is 4.15. To find the H+ concentration of the solution use the following equation -log(H+)=pH. Insert the pH into the equation to get, -log(H+) = 4.15 Rearrange the equation to get, 10^(-4.15) = H+ Finally, you can solve for H+. The hydrogen ion concentration of the vinegar solution is .0000708 M.</span>

Diamond has a density of 3.26 g/cm^3. What is the mass of a diamond that has a volume of 25 cm^3?
givi [52]

Answer:

<h2>81.5 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 25 × 3.26

We have the final answer as

<h3>81.5 g</h3>

Hope this helps you
