5 0

Answer:

              4.155 × 10²⁴ Atoms

Explanation:

Formula used,

Number of Atoms = Moles × 6.022 × 10²³ Atoms.mole⁻¹

Putting value of moles,

Number of Atoms = 6.90 mole × 6.022 × 10²³ Atoms.mole⁻¹

Number of Atoms = 4.155 × 10²⁴ Atoms

Determine the mass of 9.2 x 10^18 molecules of dinitrogen tetroxide.
steposvetlana [31]

Answer: 1.4x10-3 g N2O4

Explanation: First convert molecules of N2O4 to moles using Avogadro's Number. Then convert moles to mass using the molar mass of N2O4.

9.2x10^18 molecules N2O4 x 1 mole N2O4 / 6.022x10²³ molecules N2O4

= 1.53x10-5 moles N2O4

1.53x10-5 moles N2O4 x 92 g N2O4/ 1 mole N2O4

= 1.4x10-3 g N2O4

Write out the recipe and list all the ingredients (including the measures) of your favorite dish.
arsen [322]

The recipe for an omelet are:

<u>Ingredients</u>

  • 1 Egg
  • Salt and pepper ( 1 tablespoon )
  • Butter ( 1 tablespoon )

<u>Recipe:</u>

  • Turn on the heat and place a pan on it.
  • Add butter to the pan.
  • Crack the egg and whisk it properly.
  • Add the whisked omelet onto the pan and stir.
  • Add salt and pepper.

<h3>How to illustrate the information?</h3>

When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.

When we add butter to the pan, then the temperature of the pan was more than that of the butter.

Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.

When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.

These are the chemical reactions depicted.
