Huracan sto | Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)You can find the volume of the container using PV=nRT, just use the numbers for oxygen gas alone (convert 30.0g to moles of O2 first). Once you know the volume, you can solve to find the pressure that hydrogen gas would have in the container (again, finding n by converting from 2g to moles of H2 using the molar mass)....

First, compute the number of each atom in (H 2) 6: H: 12. Then, lookup atomic weights for each element in periodic table: H: 1.00794. Now, compute the sum of products of number of atoms to the atomic weight: Molar mass ( (H 2) 6) = ∑ Count i * Weight i =. Count (H) * Weight (H) =. The molar mass of Fe2O3, which is the chemical formula for iron(III) oxide, is 159.68 grams per mole. The molar mass is determined by adding together the atomic weight of each atom......
