Answer to Question #301320 in General Chemistry for Adrian

Question

An aqueous solution has 0.0034 g of oxygen dissolved in 1000 g of water. Calculate the

dissolved oxygen concentration of this solution in parts per million.

Answer 1

Mass of oxygen=0.0034g

Mass of water=1000g

Concentration in ppm=$\frac{mass of oxygen}{mass of solution}*10^6$

$=\frac{0.0034}{1000}*10^6$

$=3.4ppm$
