How many atoms are in 6.70 moles of sulfur (s)?

40.444 × 10∧23 atoms

Explanation:

The mole is the unit of amount in chemistry. We know that

1 mole of sulfur = 6.02× 10∧23 atoms

The number 6.02× 10∧23 is called Avogadro's number. It is define as

" Avogadro's number is the number of molecules atoms or ions in one gram molecule of a compound, one gram atom of an element or one gram ions of a substance"

For example:

1 g of hydrogen = 1 mole of hydrogen = 6.02× 10∧23 atoms of hydrogen

18 g of water= 1 mole of water= 6.02× 10∧23 molecules of water

Given data:

moles of sulfur= 6.70

number of atoms= ?

solution:

6.70 × 6.02× 10∧23 = 40.444 × 10∧23 atoms

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
