QUESTION:
A saturated solution of \(\mathrm{PbCO}_{3}\) contains 0.00011 g \(\mathrm{PbCO}_{3}\) in 100 g of water. What is this concentration in parts per million?
ANSWER:Step 1 of 2
The unit ppm is basically defined as the number of grams of solute in one million grams of solution.
\(1 \text { million }=1000000 \text { parts }\)
The conversion factor;
\(\frac{1000000 \text { parts }}{1 \text { million }}\)
\(\text { Concentration in ppm }=\left(\frac{\text { Mass of solute in grams }}{\text { Mass of solution in grams }}\right)\left(\frac{1000000 \text { parts }}{1 \text { million }}\right) \ldots . .(1)\)
