What is molar mass?

Molar mass is the mass equivalent of Avogadro's number of atoms of an element, or Avogadro's number of molecules of in a chemical compound.

Given:

The number of molecules in the sample of N₂I₆ = 3.30 X 10²³

We need to find: the number of grams in the given sample,

One mole of a substance has exactly 6.022 X 10²³ elemental units. These elemental units can be molecules, ions, or atoms depending on the substance.

If 6.022 X 10²³ molecules of N₂I₆ constitute 1 mole of the substance,

Then 1 molecule will constitute 1/6.022 X 10²³ moles of the substance.

Therefore, 3.30 X 10²³ molecules of N₂I₆ will have 3.30 X 10²³ /  6.022 X 10²³ moles

= 3.300 / 6.022

= 0.55 moles

We know that the mass of 1 mole of a substance is equal to its molar mass.

The molar mass of N₂I₆ = 2 X Molar mass of N + 6 X Molar mass of I

= 2 X 14 + 6 X 127

= 28 + 762

= 790 g

Thus, 1 mole of N₂I₆ will weigh 790g

Therefore, 0.55 moles will weigh 790 X 0.55 g

= 434.5 g

Hence, the number of grams in the given sample is 434.5 g.
