In an alloy of gold and silver, the mass of gold relates to the mass of silver as 2: 5. What is the mass of gold in an alloy containing 80g of silver?
It is known that the alloy contains 80 grams of silver. It is also known to be 5 parts. Let’s determine how many grams are in one piece. To do this, you need to divide 80 by 5:
80: 5 = 16 grams
It is known that the alloy contains 2 parts of gold. We also determined that one part contains 16 grams. To find how much gold is in the alloy, you need to multiply the number of parts by the number of grams in one part:
2 * 16 = 32 grams
Answer: The alloy contains 32 grams of gold.
