Part B: Parts Per Units Parts per million (ppm) and parts per billion (ppb) are common units for environmen- tal samples. The calculations are very similar to the percentage units. (which are es- sentially parts per hundred units). The mass units must be the same for the numerator and denominator, so these units cancel during the calculations. units; show all Please answer the following questions involving the parts per of your calculations. 7.

Concentrations of dissolved solids in water are often reported in parts per million (ppm) or parts per billion (ppb). One part per billion of a solute is equivalent to 1 ug (microgram) of that solute dissolved in 1 litre of water (i.e., 1 ppb = 1 pg/L). The toxic water crisis in Flint, Michigan in 2015 yielded test results of up to 1051 ppb of lead dissolved in tapwater. (The maximum allowable concentration set by Health Canada is 5 ppb)....
