Question #208526

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

 

1.08 dm3 - 0.585 dm3


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 logarithum10 of the concentration of hydrogen ions:

 

pH = -log10 [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 V1 the subject of the equation.
