How many molecules are there in 0.50 moles chlorine?

So the number of molecules in 0.50 moles of chlorine are 3.011 ×10²³molecules

Explanation:

Given data:

Number of moles = 0.50 mol

Number of molecules = ?

Solution:

To solve this problem we will use the Avogadro number.

The number 6.022×10²³ is called Avogadro number and it is the number of atoms in one mole of substance or number molecules in one mole of compound.

While we have to find the molecules of chlorine in 0.50 moles.

35.5 g of chlorine = 1 mole of Cl = 6.022×10²³ molecules

For 0.50 moles:

      0.50 × 6.022×10²³ = 3.011 ×10²³molecules

So the number of molecules in 0.50 moles of chlorine are

3.011 ×10²³molecules.

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
