What is the number of molecules in 1.5 moles of ammonia?

Academic Chemistry NCERT Class 9

Number moles of ammonia = 1.5

Number of molecules in 1 mole of ammonia = 6.022 × 10²³

Number of molecules in 1.5 moles of ammonia = 1.5 × 6.022 × 10²³,

Therefore, the number of molecules in 1.5 moles of ammonia is 9.033 × 10²³.
