Help please If you have 98.078 grams of Sulfuric Acid, you have
mole(s) of Sulfuric Acid (H2SO4).

1 mole of Sulfuric Acid

Explanation:

Given

Required

Determine the amount of moles

First, we need to determine the atomic mass of the acid.

-- Hydrogen

--- Sulfur

-- Oxygen

So:

Number of moles (n) is then calculated as thus:

(approximated).

Hence, there is 1 mole of Sulfuric Acid
