Question

How many moles are in 1.23 x 1024 molecules of oxygen gas.

Answer 1

6.02 x 10²³ molecules makes up 1 mole of any substance

1.23 x 10²⁴molecules will make up = 2.04moles

Answer 2

2.04moles

Step-by-step explanation:

Given parameters:

Number of molecules = 1.23 x 10²⁴molecules

Unknown:

Number of moles of oxygen gas = ?

Solution:

To solve this problem;

6.02 x 10²³ molecules makes up 1 mole of any substance

1.23 x 10²⁴molecules will make up
`(1.23 x 10^(24) )/(6.02 x 10^(23) )` = 2.04moles
