The mass or weight w of the desired 18 % copper alloy may be calculated from the masses of the two kinds of distinct alloys specified to be mixed and their masses, M for the copper-rich alloy and m for the lower copper alloy, from the formula 0.23M + 0.14m = 0.18 (M + m). Furthermore, M + m is stated to be 90, so that M = 90 - m. Therefore
0.23(90 - m) + 0.14m = 0.18 X 90 = 16.2. Multiplying out and collecting like terms results in 20.7 - (0.23 + 0.14)m = 16.2 or 0.09m = 4.5 or m = 50 ounces. M = 90 - 50 = 40 ounces.
What else can I help you with?
A statute is made of bronze which is an alloy of about 80 percent copper and 20 percent tin Which metal is the higher concentration in this bronze statue?
There is a higher concentration of copper in a bronze statue. This is because there is a higher percentage of bronze metal in the statue.
Is brass a non ferrous alloy or a non ferrous metal?
yes. It is a non ferrous metal in that it is an alloy of copper and zinc. Ferrous refers to iron, the elemental symbol for iron is Fe.
Is copper pure metal or alloy?
An alloy is a mixture of two or more elements where the main component is metal. Copper is a pure metal. Alloys are useful because most pure metals are too soft, brittle, or reactive for practical use.
What elements are in bronze?
Bronze is an alloy composed primarily of copper and tin, with the proportion of these two elements varying based on the desired characteristics of the bronze. Other elements, such as aluminum, manganese, or silicon, may also be added in smaller amounts to modify its properties.
What word is used to describe a mixture that is 85 percent copper and 15 percent tin?
The word used to describe a mixture that is 85% copper and 15% tin is bronze. Bronze is an alloy made by mixing copper and tin in various proportions to achieve different properties like increased durability and strength.
How much of an alloy that is 40 percent copper should be mixed with 400 ounces of an alloy that is 70 percent copper in order to get an alloy that is 50 percent copper?
200 ounces.
How much of an alloy that is 10 percent copper should be mixed with 400 ounces of an alloy that is 70 percent copper in order to get an alloy that is 20 percent?
How much of an alloy that is 10% copper should be mixed with 400 ounces of an alloy that is 70% copper in order to get an alloy that is 20%
How much of an alloy that is 20 percent copper should be mixed with 300 ounces of an alloy that is 60 percent copper in order to get an alloy that is 30 percent copper?
900 ounces. Since this contains 20% copper, The copper content will be 180 ounces. The original 300 ounces contain 30% copper which is also 180 ounces. Hence in the resulting mixture of 1200 ounces (300+900), the total copper is 360 ounces (180+180). Hence the copper content of resulting mixture is 360/1200 which is 30%
How much of an alloy that is 30 percent copper should be mixed with 600 ounces of an alloy that is 90 percent copper in order to get a alloy that is 60 percent copper?
Since the percentages of copper in the two components to be mixed are symmetric about the desired result, the answer is that the same amounts should be used. 600 ounces of the 30% copper.
How much of alloy that is 20 percent copper should be mixed with 200 ounces of an alloy that is 50 percent copper in order to get an alloy that is 30 percent copper?
LET X be the weigh tof the 20% alloy and then the total weight of the 30% alloy is 200 +X then 0.20X + .50 (200) = .30 (200 +X) .20X + 100 = 60 + .3X 40 = .1X 400 = X = 400 ounces
Why copper is an alloy?
copper is NOT an alloy, it is an elemental metal
A statute is made of bronze which is an alloy of about 80 percent copper and 20 percent tin Which metal is the higher concentration in this bronze statue?
There is a higher concentration of copper in a bronze statue. This is because there is a higher percentage of bronze metal in the statue.
How much of an alloy that is 40 copper should be mixed with 500 ounces of an alloy that is 70 copper in order to get an alloy that is 50 copper?
Let ( x ) be the amount of the 40% copper alloy needed. The equation based on the copper content is: [ 0.40x + 0.70(500) = 0.50(x + 500) ] Solving this equation, we find: [ 0.40x + 350 = 0.50x + 250 ] [ 100 = 0.10x ] [ x = 1000 ] Thus, you need to mix 1000 ounces of the 40% copper alloy with 500 ounces of the 70% copper alloy to obtain an alloy that is 50% copper.
How much of an alloy that is 20 should be mixed with 100 ounces of an alloy that is 70 copper in order to get that 40 copper?
To create an alloy with 40% copper, you would need to mix equal parts of the 20% alloy with the 70% alloy. This means you need to mix 50 ounces of the 20% alloy with 50 ounces of the 70% alloy to achieve the desired 40% copper content in the final alloy.
What alloy is 57 percent silver and 40 percent copper and 3 percent tin?
The alloy you are describing with 57% silver, 40% copper, and 3% tin is called "sterling silver." It is a popular metal choice for jewelry and silverware due to its durability and shine.
Silver metal reaction with copper metal?
Alloy
How much of an alloy that is 10 percent copper should be mixed with an alloy that is 80 percent copper in order to get an alloy that is 30 percent copper?
Let me reduce that to an equation for you: 10x + 80(1-x) = 30; solve for x.
