Question

How many moles are in 6.777 x 1023 atoms of CO2. Watch your significant figures. Question 2 options: 1 atoms CO2 1.125 moles CO2 1.13 moles 1.13 atoms CO2

Answer 1

1.13moles

Step-by-step explanation:

Given parameters:

Number of atoms = 6.777 x 10²³ atoms

Unknown:

Number of moles = ?

Solution:

A mole of a substance contains the avogadro's number of particles

6.02 x 10²³ particles = 1 mole

6.777 x 10²³ atoms will contain
`( 6.777 x 10^(23) )/(6.02 x 10^(23) )` = 1.13moles
