Answer:
1 mole of Sulfuric Acid
Explanation:
Given
[tex]Compound = H_2SO_4[/tex]
[tex]Grams = 98.078[/tex]
Required
Determine the amount of moles
First, we need to determine the atomic mass of the acid.
[tex]H = 1.008g[/tex] -- Hydrogen
[tex]S = 32.065[/tex] --- Sulfur
[tex]O =15.999[/tex] -- Oxygen
So:
[tex]H_2SO_4 = H * 2 + S + O * 4[/tex]
[tex]H_2SO_4 = 1.008 * 2 + 32.065 + 15.999 * 4[/tex]
[tex]H_2SO_4 = 2.016 + 32.065 + 63.996[/tex]
[tex]H_2SO_4 = 98.077g[/tex]
Number of moles (n) is then calculated as thus:
[tex]n = \frac{Grams}{Atomic\ Mass}[/tex]
[tex]n = \frac{98.078g}{98.077g}[/tex]
[tex]n = \frac{98.078}{98.077}[/tex]
[tex]n = 1.00001019607[/tex]
[tex]n =1[/tex] (approximated).
Hence, there is 1 mole of Sulfuric Acid
