Web5 feb. 2024 · The molar mass of molecular hydrogen is about 2 mg/milimole and so 1 mg is about the same as 0.5 moles so 1 ppm = 1 mg/L =0.5 mM. The concentration of hydrogen gas (H2) in conventional water (e.g. tap, bottled, filtered, etc.) is about 8.65 x 10-7 mg/L. In other words, there is less than one eight-millionth of a mg of H2.

(100g carbon / 12.011 g ) = 8.33 moles of carbon. Four times as many hydrogen atoms are needed as carbon atoms to make methane, , so four times as many moles will be required also: (4 moles H / 1 mole C) x 8.33 moles C = 33.3 moles of hydrogen. Since the atomic weight of hydrogen is 1.008, this corresponds to.
