A sample has a nitrate concentration of 4.39 mg/L (4.39 ppm nitrate). Calculate its molar concentration (in moles/L). (This primarily involves unit conversions).

Explanation:

The nitrate concentration of the sample =

Molar mass of

The molar concentration is obtained when we divide the concentration by its molar mass in the approriate units.

The molar concentration is

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
