Question

The chemical atomic mass of hydrogen, with the two stableisotopes 1H and 2H (deuterium), is1.00798.
Use this value to determine the natural abundanceof 1H isotope. Express your answer to the nearestthousandth of a percent Use this value to determine thenatural abundance of 2H isotope. Express your answer to the nearestthousandth of a percent. The chemical atomic mass of hydrogen, with the two stableisotopes 1H and 2H (deuterium), is1.00798.

Explanation / Answer

let the abundance fraction of 1H isotope is f we have as the mass number given to be 1.00798. =f+2*(1-f) hence f=2- 1.00798.=0.99202 =99.202 percent and 1-f=abundance of 2Hisotope.=7.98*10-3=0.798percent
