Calculate the number of molecules in 3.0000 moles of CO2

The answer is 1.806 × 10²⁴ CO2 molecules

Explanation:

The numbers of molecules can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities.

From the question we have

N = 3 × 6.02 × 10²³

We have the final answer as

1.806 × 10²⁴ CO2 molecules

Hope this helps you

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

No is the answer to the question
