What mass of H2SO4 contains 32 gram of oxygen?
Solution : `(w_(O))/(w_(H_(2)SO_(4)))="constant"rArr(64)/(98)=(32)/(w_(H_(2)SO_(4)))rArrw_(H_(2)SO_(4))=49gm`.
What is the mass of O in one mole of H2SO4?
98.079 g/molSulfuric acid / Molar mass
What is the total mass of oxygen?
The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
How do u calculate mass?
Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.

How many oxygen atoms are present in 49g of H2SO4?
If you divide 49 g by 98.1 g/mole you get . 4995 moles. Multiply this by 6.022 x 10^23 to get 3.008 x 10^23 molecules of H2SO4 in 49 g. If you multiply this by 4 (there are 4 oxygen atoms in each molecule) you get 1.203 x 10^24 atoms of oxygen.
What is the molecular mass of sulfuric acid H2SO4?
98.079 g/molSulfuric acid / Molar mass
How many moles of oxygen are present in 24.5 g of sulphuric acid?
So, 24.5 g of H2SO4 contains = (64/98)×24.5 g of oxygen = 16 g of oxygen. Therefore, Moles of oxygen is = mass/molar mass = 16/16 = 1 mole of oxygen.
What is mass of one molecule of H2SO4?
Hence, molecular weight of H2SO4 is 98.08 g/mol.
