Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol This is the number of moles in ...
Do a quick conversion: 1 grams Hydrogen Iodide = 0.0078178497301396 mole using the molecular weight calculator and the molar mass of HI.
"One mole" is close to the number of atoms in a gram of hydrogen. It’s also, by chance, a decent ballpark guess for the number of grains of sand on Earth. A mole is also a type of burrowing mammal. There are a handful of types of moles, and some of them are truly horrifying...

This ratio is the ratio of stoichiometric numbers in the equation. So the equation is: 2H2 + O2 -->2H2O We can still deduce the stoichiometry of this reaction even if we do not know the mass of oxygen that reacted. The ratio of hydrogen to water is 1 : 1. But there...
Why not? Remember that hydrogen is one of the diatomic gases. There is really no such thing as loose hydrogen atoms. The total mass of a single hydrogen diatomic molecule (H2) is 2. 016 AMU. A mol of hydrogen gas has a mass of 2.016 grams. In that 2.016 gram mass is Avogadro’s ...
calculate the mass in grams of 3.6 mol of h 2 so 4 . solution look for the atomic masses of hydrogen, sulfur and oxygen. h = 1.008 s = 32.06 o = 16 therefore, the molecular mass of h 2 so 4 is 2(1.008) + 32.06 + 4(18) = 106.076 hence, one mole of h 2 so 4 weights ...
