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

Respuesta :

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
