Question

no of moles in 6.022*10^23 molecules of NH3​

Answer 1

Answer:

The molar mass of NH3 is equalled to 17 gram. Moles of NH3 in 8.5 gm =8.5/17=0.5thus molecules in half mole NH3 is 6.022×10^23×0.5and atoms in half mole NH3=0.5× 6.022×10^23×48.5/17 = 0.50. 5 moles of NH3 are present. 0.5×6.022×10^23 = 3.011×10^23 molecules of NH3.
