Question

Choose the option that would convert mg/L

into molarity (mol/L).

A. Convert mg/L to get g/L then multiply by the volume (L).

B Convert mg/L to g/L then divide by molar
mass (g/mol).

C. Convert mg/L to g/L then divide by the volume (L).

D. Convert mg/L to g/L then divide by the
number of moles (mol).

Answer 1

Option B is the correct choice to convert mg/L to molarity; it involves converting mg/L to g/L and then dividing by the substance's molar mass (g/mol).

Step-by-step explanation:

The correct option for converting mg/L into molarity (mol/L) is option B: Convert mg/L to g/L then divide by molar mass (g/mol). Here's how you do it:

1. Convert the concentration from mg/L to g/L by dividing by 1000, because there are 1000 milligrams in a gram.
2. Divide the concentration in g/L by the molar mass of the substance (g/mol) to find the molarity.

Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution (mol/L).

Answer 2

Answer: Not A, its B

Explanation: B
