Question

Residues of the herbicide atrazine 1C8H14ClN52 in water can be detected at concentrations as low as 0.050 mg>L. Express this concentration of atrazine in the following units:
(b) Molarity

Accepted Answer

Hello. In this primary told sample of water was detected to have 0.015 mg per liter of dioxin in which is an insecticide to express its concentration in terms of hilarity were given the molar mass of Diazinon parity recall has units of moles per liter. So we already have our units volume. In terms of leaders, we need to convert from mass to moles and we can do that using the molar mass. So we'll begin with what we're given, which is the concentration of days non in milligrams per leader, we can convert our milligrams two g so that our units of milligrams cancel and then we can make use of the molar mass. So we have three and 4.35 g for every mole And our units of g cancel. So we're left with moles per liter, which is more clarity. This works out to 4.9 times 10 to the -8 Mueller. This concentration corresponds then to answer B. Thanks for watching.
