How many formulas units are in 3.11 mole of Ca(NO3)2 can you show your work by step by step correct answer
Lyrx [107]

Answer:

18.73× 10²³ formula units

Explanation:

Given data:

Number of moles of Ca(NO₃)₂ = 3.11 mol

Number of formula units = ?

Solution:

Avogadro number:  

"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance"  

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

Number of formula units of Ca(NO₃)₂:

1 mole contain 6.022 × 10²³ formula units

3.11 mol ×  6.022 × 10²³ formula units / 1 mol

18.73× 10²³ formula units

Match each interaction type to the correct amount of potential energy.
Zigmanuir [339]

The type of energy which is present between the repulsion interaction is the highest potential energy.

<h3>What is potential energy?</h3>

Potential energy is the amount of energy that is possess by any body with respect to the electric charge posses in that and other factors also.

  • When molecules have a high attraction force then they have the low potential energy in them.
  • When molecules have a great repulsion between them then they have the great potential energy in them.
  • And molecules have the middle amount of potential energy then they have the balanced interaction.

Hence, molecules in which repulsion interaction is present will have highest potential energy.
