Answer:
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements.
Explanation:
Answer:
30g
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.
