Question

CALCULATE THE NUMBER OF MOLES AND MOLECULES OF AMINO NH3 GAS IN VOLUME 6 7.2 AND THREE OF ITS MEASURE AT STP​

Answer 1

Answer:

3 moles and 3Na molecule are present in 67.2 L of ammonia gas

Explanation:

According to the definition of Mole

22.4 L volume occupied by 1 mole of gas

so 67.2 L will be occupied by ($\frac{1}{22.4}$) × 67.2=3 mole

From defination

                  One mole of ammonia has Na ( Avagogadros number of particle)

So 3 mole of ammonia will have 3Na molecules.
