What is the wavelength (in meters) of an electron travelling at 8.10 x 106 m s-l? Remember that 1 Joule = 1 kg m’s-?

The correct answer is b.hoped i you

The think of process to make something successful

Ithink it's the third answer

Moles of co₂ = 2.35/44 = 0.0534 mole.from ideal gas equation pv=nrt,  t = 18+273k = 291 kelvin.∴px5 = 0.0534x0.0821x291∴p = 0.0534x0.0821x291/5 = 0.2551 atm.now, 1 atm = 760 mm of hg  ∴ 0.02551 atm = 0.02551 x 760 = 19.38 mm of hg
