an alloy is formed by mixing 4.5g copper and 2.8g zinc.how much alloy of similar kind can be formed by using 13.5g copper?
Since 13.5 = 3*4.5, 3 times as much zinc is also used.
21.9 g
To find out how much alloy can be formed using 13.5g copper, we need to determine the ratio of copper to zinc in the original alloy and then use that ratio to calculate the amount of zinc required to form the new alloy.
The original alloy is formed by mixing 4.5g of copper and 2.8g of zinc. Let's calculate the ratio of copper to zinc:
Copper:Zinc = 4.5g:2.8g = 45:28
Now, we can use this ratio to calculate the amount of zinc needed to form the new alloy using 13.5g of copper:
Zinc = (13.5g of copper) x (28g of zinc / 45g of copper)
Zinc = (13.5g of copper) x (28/45)
Zinc = 8.4g
Therefore, we can form an alloy of a similar kind by using 13.5g of copper and 8.4g of zinc.
To determine how much alloy can be formed using 13.5g of copper, we need to use the ratio of copper to zinc in the original alloy.
First, find the ratio of copper to zinc in the original alloy:
Copper:Zinc = 4.5g:2.8g
Next, we can use this ratio to find the amount of zinc present in 13.5g of copper.
Let's set up a proportion:
4.5g copper / 2.8g zinc = 13.5g copper / x grams of zinc
Cross-multiplying, we get:
4.5g copper * x grams of zinc = 2.8g zinc * 13.5g copper
Simplifying, we have:
4.5x = 37.8
Now, divide both sides of the equation by 4.5 to solve for x:
x = 37.8 / 4.5
x ≈ 8.4g
Therefore, approximately 8.4g of zinc would be needed to form an alloy of a similar kind using 13.5g of copper.
