Calculate the number of molecules in 0.013 moles of ammonia

1 mole = 6.02x10^23 molecules/particles Therefore, 0.013 moles = 0.013 x 6.02x10^23 = 0.078299*10^23

u know that the avogadro number is equal to 6.022 * 10^23 per mole . in 0.013 mole of NH3 the molecules present is equal to 0.013*6.022*10^23 molecules = 7.8 * 10^21 molecule is pr...
