How many moles in h2 gas
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. WebAs hydrogen gas naturally occurs in a diatomic state, it is true that there is only one mole …
