Are there are more atoms in a glass of water than stars in the observable universe?

Answer 1

Probably, yes.

astronomers have put current stellar population at roughly 70 billion trillion (#70*10^22#)

Since a glass of water has many moles of water , and each mole contains about #22*10^23# molecules of water and each molecule contains 3 atoms , the scales tip heavily towards the glass of water

No, there aren't more atoms in a glass of water than there are stars in the observable universe. A glass of water has about 10^24 molecules, each of which is made up of three atoms (two hydrogen atoms and one oxygen atom). As a result, there are far fewer atoms in a glass of water than there are stars in the observable universe.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
