The water treatment plant adds chlorine gas to the municipal water supply to control microorganisms. If a technician adds Cl2 at a rate of 1 mg per liter of water,
what is the molar concentration of chlorine in the drinking water?

1 × 10⁻⁵ M

Explanation:

Step 1: Given data

Step 2: Convert the concentration of chlorine from mg/L to g/L

We will use the conversion factor 1 g = 10³ mg.

1 mg/L × 1 g/10³ mg = 1 × 10⁻³ g/L

Step 3: Convert the concentration of chlorine from g/L to mol/L (molar)

We will use the molar mass of chlorine: 70.91 g/mol.

1 × 10⁻³ g/L × 1 mol/70.91 g = 1 × 10⁻⁵ mol/L = 1 × 10⁻⁵ M

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
