What is the mass of sulfur in 250 grams of sulfuric acid?

=250⋅g98.08⋅g⋅mol−1=2.55⋅mol . And thus there are 2.55⋅mol×32.06⋅g⋅mol−1 of sulfur approx. 82⋅g sulfur. Sulfuric acid can be obtained at 98% concentrations but this is still an aqueous solution with [H2SO4]≅18⋅mol⋅L−1 .

How do you calculate the mass of oxygen?

Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.

How many moles of oxygen are in H2SO4?

4 moles
