Seven diatomic elements are H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂.

<h3>Which are diatomic molecules?</h3>

Diatomic molecules are those molecules in which two atoms of same elements are present, and they are combined to attain the stability.

The seven diatomic molecules which are exist in the chemistry are:

  • Hydrogen gas (H₂)
  • Chlorine gas (Cl₂)
  • Nitrogen gas (N₂)
  • Fluorine gas (F₂)
  • Bromine gas (Br₂)
  • Iodine gas (I₂)
  • Oxygen gas (O₂)

Hence H₂, Cl₂, N₂, F₂, Br₂, I₂ and O₂ are 7 diatomic molecules.

Commercial concentrated aqueous ammonia is 28% nh3 by mass and has a density of 0.90 g/ml. what is the concentration of ammonia
patriot [66]

Answer:- 14.9 M

Solution:- Given commercial sample of ammonia is 28% by mass. Let's say we have 100 grams of the sample. Then mass of ammonia would be 28 grams.

Density of the solution is given as 0.90 grams per mL.

From the mass and density we could calculate the volume of the solution as:

100g(\frac{1mL}{0.90g})

= 111 mL

Let's convert the volume from mL to L as molarity is moles of solute per liter of solution.

111mL(\frac{1L}{1000mL})  

= 0.111 L

Now, we convert grams of ammonia to moles on dividing the grams by molar mass. Molar mass of ammonia is 17 gram per mole.

28g(\frac{1mole}{17g})

= 1.65 mole

To calculate the molarity we divide the moles of ammonia by the liters of solution:

molarity=\frac{1.65mole}{0.111L}

= 14.9 M

So, the molarity of the given commercial sample of ammonia is 14.9 M.
