That tells us how many moles of molecules are in the monolayer. C7. Calculate the value of Avogadro’s number. We have the number of molecules in the monolayer now as both a count of single molecules and a count of moles of molecules. The ratio of the two is Avogadro’s number. We’re in the ball park.

(b) Calculate the number of moles of nitrogen in 7 grams of nitrogen. [2] Ans. (a) The volume occupied by 1 mole (1 gram-molecule) of a gas at STP is called molar volume of the gas. Its experimental value is 22.4 dm3 at STP. (b) 1 g-molecule of nitrogen = 2 × 14 = 28 g. Now, 28 g of nitrogen = 1 mole ∴ 7 g of nitrogen = 7 18 moles = 0.25 moles.
