Question

In a certain​ chemical, the ratio of zinc to copper is 3 to 17. A jar of the chemical contains 799 grams of copper. How many grams of zinc does it​ contain?

Answer 1

To find the amount of zinc in a mixture with a zinc to copper ratio of 3 to 17 and 799 grams of copper, set up a proportion and solve for x. The result is approximately 141 grams of zinc in the jar.

Step-by-step explanation:

The student's question is asking to find the amount of zinc in a chemical mixture based on the given ratio of zinc to copper. We know the total mass of copper is 799 grams and the ratio of zinc to copper is 3 to 17.

To determine the amount of zinc, we can use the following proportion where x is the grams of zinc:

• zinc/copper = 3/17 = x/799

To solve for x, we cross multiply:

• Multiply 3 by 799 to get 2397.
• Divide this result by 17 to find the grams of zinc.

• x = 2397 / 17
• x = 141 grams

Therefore, the jar contains approximately 141 grams of zinc.

Answer 2

let's see what to do buddy...

Step-by-step explanation:

`(zinc)/(copper) = (3)/(17) \\ \\ (zinc)/(799) = (3)/(17)`

Multiply the sides of the equation by 799

`zinc = (3)/(17) * 799 \\ \\ zinc = (3)/(17) * 17 * 47 \\ \\ zinc = 3 * 47 = 141`

So A jar of the chemical contains 141 grams of zinc.

And we're done.

Thanks for watching buddy good luck.
