Heavy water has a formula D2O, and semi-deuterated water has the formula DHO, where D stands for deuterium. Using the data below, etimate the percentages of D2o and DHO present in natural water
Element Isotope isotopic mass(u) Natural Abundance (%) Protons Neutrons
Hydrogen ^1H 1.0078250321 99.9850 1 0
Deuterium ^2H 2.0141017780 0.0115 1 1
