How many oxygen atoms are there in 5 molecules of CH3FO

1 mole of a substance contains Avagadro’s number of particles,

i.e. 6.023*10^23

By unitary method,

5 moles of oxygen contains 5 times the Avagadro’s number of particles

i.e. 5* (6.023*10^23) = 3.0115*10^24 number of particles.

Now, the further answer depends on what particles the question concentrates on.

If number of atoms are asked , the above answer must be multiplied by 2, because oxygen is a diatomic gas and each atom contributes to be a particle.

therefore, 5 moles of oxygen has 6.023*10^24 atoms.

If number of molecules asked, the above answer is directly written...

Step-by-step explanation:

A full week is 7 days. Each day has 24 hours, so there are

7x24 = 168 hours in a week. Each hour is 60 minutes, so there are

168x60 = 10,080 minutes in a full week.

1/10 of that is:

10,080 divided by 10 = 1,008 minutes
