Question

There is 60.0% oxygen by mass in a certain compound of sulfur and oxygen. Percent by mass is a ratio of the number of grams of a particular component to 100 g of the total sample. How many grams of sulfur are in a 14.6 g sample of the compound?

Answer 1

Answer: The mass of sulfur in the given amount of sample is 5.84 grams.

Explanation:

We are given:

60.0% oxygen by mass in a compound

This means that 60 grams of oxygen are present in 100 grams of a compound

So, mass of sulfur in the compound is 40 grams

Given mass of the compound = 14.6 grams

Applying unitary method:

In 100 grams of a compound, the mass of sulfur is 40 grams

So, in 14.6 grams of a compound , the mass of sulfur will be = $\frac{40}{100}\times 14.6=5.84g$

Hence, the mass of sulfur in the given amount of sample is 5.84 grams.
