What is the number of cations is present in 1.17 g of sodium chloride? given na=6*10power 23 mol

Explanation:

Hello,

In this case, one knows that sodium chloride's formula is NaCl, therefore, the amount of cations is computed via the following stoichiometric relationship, considering the Avogadro's number to relate moles of sodium cations with their actual amount:

Best regards.

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).
