Final answer:

In a compound containing 15% sulfur, 30g of sulfur corresponds to a total mass of 200g of the compound.

Step-by-step explanation:

If a compound contains 15% sulfur and you have a total of 200g of this compound, to find the mass of sulfur you would multiply the total mass of the compound by the percentage of sulfur present.

To calculate this, convert the percentage to its decimal form (15% is 0.15), and then carry out the multiplication:

Mass of sulfur = (Percentage of sulfur in decimal form) x (Total mass of compound)

Mass of sulfur = 0.15 x 200g = 30g of sulfur.

Answer:

30g

Step-by-step explanation:

According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.

The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:

Mass of sulfur = 15% of 200g

15/100 × 200g

15 × 2

30g

Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
