Question

1-How can you find out the number of an atom if moles are given to you?
2-How can you find out mass if moles are given to you?
3-Can you find out the number of atoms?
4-How can you find numbers of atoms or number of molecules if moles are given to you?
5-What are avocados numbers?

Answer 1

1 . Number of atoms in 1 mole = 6.022× 10^(23)

number of atoms if moles are given

= number of moles × 6.022× 10^(23)

2 . 1 mole = 1 Gram atomic mass

Gram atomic mass = atomic mass in grams

mass if moles are given

= number of moles × atomic mass (in grams)

3 . Number of atoms in 1 mole = 6.022× 10^(23)

5 . 6.022× 10^(23) is known as Avogadro number

Hope this will help....
