Hydrocarbons are organic compounds composed entirely of hydrogen and carbon. A 0. 1647 g sample of a pure hydrocarbon was burned in a combustion apparatus to produce 0. 4931 g of co2 and 0. 2691 g of water. Determine the empirical formula; enter as c#h#, so c1h1.

explanation:

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
