340.000 ppm
34,000 ppm
3,400 ppm

340.000 ppm

Explanation:

Parts per million (ppm) is a unit of measure for concentration that measures the number of units of substance per million units of the set. It is a concept homologous to the percentage, only in this case it is not parts per percent but per million. The ppm calculation method is different for solids, liquids and gase. There are many formulas, however in this case, you can use this fact:

Using Cross-multiplication:

Solving for :

Therefore, the concentration of a 34% solution converted to parts per million is:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
