You decide it is time to clean your pool since summer is quickly approaching. your pool maintenance guide specifies that the chlorine, cl 2, the concentration of the pool should be between 1 and 3 ppm. in order to determine if your pool is safe to swim in, you send a sample of pool water to a chemist for analysis of the cl 2 content. the chemist reports a chlorine concentration of 4.23 × 10 − 5 m. convert the concentration of cl 2 to parts per million ( ppm ).

3.00 ppm

Explanation:

The molar concentration of Cl₂ is 4.23 × 10⁻⁵ M = 4.23 × 10⁻⁵mol Cl₂/L. We want to convert this concentration to parts per million 1 ppm = 1mg/L.

We will use the following relations:

Then, we can use proportions:

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
