27 + (35,5 + 2* 16) * 3 = 229.5 g/mol
Water is whats left so then that evaporates
mass h

</h3>
Explanation:
molar mass is equal to number of mass over moles we take 14.19 over17 molar mass of ammammonium equals 0.8347 incase of moles. 1H=1Nh3 ,so. n.H=0.8347 Mr=2 ,M.H=? Mr=m/n. 0.8347x2=1.669grams
Use the de Broglie relationship between mass and wavelength (lambda).
lambda=h(Planck's constant)/[(mass)*(volume)]
lambda=6.626*10^-34/[(9.76*10^6)*(9.1094*10^-31)]
=7.45*10^-11 m
Can you elaborate this a little more?
