Question

Help please

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

Answer 1

1 mole of Sulfuric Acid

Step-by-step explanation:

Given

`Compound = H_2SO_4`

`Grams = 98.078`

Required

Determine the amount of moles

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

`H = 1.008g` -- Hydrogen

`S = 32.065` --- Sulfur

`O =15.999` -- Oxygen

So:

`H_2SO_4 = H * 2 + S + O * 4`

`H_2SO_4 = 1.008 * 2 + 32.065 + 15.999 * 4`

`H_2SO_4 = 2.016 + 32.065 + 63.996`

`H_2SO_4 = 98.077g`

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

`n = (Grams)/(Atomic\ Mass)`

`n = (98.078g)/(98.077g)`

`n = (98.078)/(98.077)`

`n = 1.00001019607`

`n =1` (approximated).

Hence, there is 1 mole of Sulfuric Acid
