Question

A compound is analyzed and found to be 50% sulfur and 50% oxygen. If the total amount of the sulfur oxide is 12.5 g, how many grams of sulfur are there? Show work.

Answer 1

Answer:

25.0g is the mass of sulfur

Explanation:

The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.

To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:

Moles O = Moles S:

12.5g O * (1mol / 16g) = 0.781 moles

Mass S:

0.781 moles * (32g / mol) =

25.0g is the mass of sulfur
