In a chemical compound there are 3 parts zinc for every 16 parts copper, by mass. A piece of the compound contains 320 grams of copper. Write and solve an equation to determine the amount of zinc in the chemical compound
Since there is 320 grams of copper, than 16 multiplied by 20 will be 320. So then you have to multiply 3 times 20 which is 60. So 3:16 multiplied by 20 will be 60:320.
ANSWER: 60 parts zinc. Hope this helped. Have a great day! A brainliest and (or) thank you is always appreciated. Goodbye!
