The following balanced equation shows the formation of sulfur dioxide. s + o2 so2 how many moles of sulfur are needed to produce 15.0 mol of sulfur dioxide? a. 7.50 mol b. 10.5 mol c. 15.0 mol d. 30.0 mol

actually the answer is C. 15.0 on ed

Ans: C) 15.0 mol

Given:

Chemical reaction:

S + O2 → SO2

Moles of SO2 produced = 15.0 mol

To determine:

Moles of S needed

Explanation:

Based on the stoichiometry of the given reaction:

1 mole of S is required to produce 1 mole of SO2

Therefore, # moles of S required to produce 15.0 mol of SO2 is

= 15.0 mol SO2 * 1 mol S/1 mol SO2 = 15.0 mol S
