Question #208526

5). Solve the following problem, giving answers with the correct number of decimal places.

**1.08 dm**^{3}** - 0.585 dm**^{3}

7). The pH scale is the most common logarithmic scale you will encounter on the course. The pH of a solution is defined as the negative logarithum_{10} of the concentration of hydrogen ions:

pH = -log_{10} [H^{+} (aq) ]

The hydrogen ion concentration can be determined by taking the antilog of the negative pH value

[H^{+} (aq) ] = 10^{-pH}

What is the concentration of aqueous hydrogen ions in a solution of pH 6.7?

8). The combined gas equation is given below;

Rearrange the equation making V_{1} the subject of the equation.

Expert's answer

5)0.495dm3

7)4.73M

8)"V_1=\\frac {T_1\u00d7P_2\u00d7V_2}{P_1\u00d7T_2}"
