An organic compound is made up of 0.72g of carbon, 0.16g of hydrogen and 0.64g of oxygen. Calculate the emperical formula of the compound (c=12, h=1, o=16)

"electrical energy" transforms to "thermal energy".hope my answer has you : )

D=m/v =57.9/3 = 19.3 g/cm^3

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
