1. 2.408 x 10²⁴ molecules

2. 2.408 x 10²⁴ atoms

3. 4.816 x 10²⁴ atoms

<h3>Further explanation</h3>

Given

4 moles of Carbon dioxide.

Required

Carbon dioxide molecules

Carbon atoms

Oxygen atoms?

Solution

1 moles = 6.02 x 10²³ particles(molecules, atoms, ions)

1. Carbon dioxide molecules :

= 4 moles x 6.02 x 10²³

= 2.408 x 10²⁴ molecules

2. The number of Carbon atoms

In CO₂, there is 1 atom C, so the number of atoms :

= 1 x 2.408 x 10²⁴

= 2.408 x 10²⁴ atoms

3. The number of Oxygen atoms :

In CO₂, there is 2 atom O, so the number of atoms :

= 2 x 2.408 x 10²⁴

= 4.816 x 10²⁴ atoms

What is the average atomic mass of chlorine if the mass of one isotope is 34.97 amu and has a p?er cent abundance of 75.77%. The

pishuonlain [190]

Answer : The average atomic mass of chlorine is, 32.37 amu

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

$\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i$

As we are given that,

Mass of isotope 1 = 34.97 amu

Percentage abundance of isotope 1 = 75.77 %

Fractional abundance of isotope 1 = 0.7577

Mass of isotope 2 = 36.97 amu

Percentage abundance of isotope 2 = 24.23 %

Fractional abundance of isotope 2 = 0.2423

Now put all the given values in above formula, we get:

$\text{Average atomic mass of element}=\sum[(34.97\times 0.7577)+(24.23\times 0.2423)]$

$\text{Average atomic mass of element}=32.37amu$

Therefore, the average atomic mass of chlorine is, 32.37 amu
