S + O2 = SO2

1 mole S ------------- 1 mole SO2
( moles S ) --------- 15.0 moles SO2

moles S = 15.0 x 1 / 1

moles S = 15.0 / 1

= 15.0 moles S

Answer : The number of moles of sulfur needed are, 15 moles

Explanation : Given,

Moles of sulfur dioxide = 15 mole

The balanced chemical reaction will be,

$S+O_2\rightarrow SO_2$

By the stoichiometry we can say that, 1 mole of sulfur react with 1 mole of oxygen gas to give 1 mole of sulfur dioxide as a product.

From the balanced chemical reaction we conclude that,

As, 1 mole of sulfur dioxide produces from 1 mole of sulfur

So, 15 moles of sulfur dioxide produces from 15 moles of sulfur

Therefore, the number of moles of sulfur needed are, 15 moles
