Find first the relative molecular mass of sulfuric acid.

In sulfuric acid, there is 2 hydrogen atoms, 1 sulfur atom and 4 oxygen atoms.
1 Hydrogen atom has a relative mass of 1.
1 Sulfur atom has a relative mass of 32.
1 Oxygen atom has a relative mass of 16.

Find the relative molecular mass of sulfuric acid first using these.

Then, 1 molecule has that much relative mass. Find the relative mass of 100 such molecules for the first part.

Post what you get for this part, then we'll proceed to the others.
