Answer 1

Calculation of the Alloy's Weight

To find the weight of the alloy, we need to know the total weight of the alloy and the percentage composition of each element. From the given information, we know that the alloy consists of 38 parts copper, 5 parts tin, and 5 parts lead.

Let's assume the total weight of the alloy is x grams.

According to the given composition, the weight of lead in the alloy is 250 grams. Therefore, we can set up the following equation:

5/24 * x = 250

Solving this equation will give us the value of x, which represents the total weight of the alloy.

Calculation of Copper and Tin in the Alloy

Once we have the total weight of the alloy, we can calculate the weight of copper and tin using their respective percentages.

From the given composition, we know that the alloy consists of 38 parts copper and 5 parts tin.

To find the weight of copper, we can use the following equation:

38/45 * x = weight of copper

To find the weight of tin, we can use the following equation:

5/12 * x = weight of tin

Solving these equations will give us the weights of copper and tin in the alloy.

Let's calculate the values.

Calculation Steps

1. Calculate the total weight of the alloy: - 5/24 * x = 250 - Solve for x: x = 250 * 24/5

2. Calculate the weight of copper: - 38/45 * x = weight of copper - Substitute the value of x: (38/45) * (250 * 24/5)

3. Calculate the weight of tin: - 5/12 * x = weight of tin - Substitute the value of x: (5/12) * (250 * 24/5)

Calculation Results

After performing the calculations, we find that: - The total weight of the alloy is approximately 1,200 grams. - The weight of copper in the alloy is approximately 800 grams. - The weight of tin in the alloy is approximately 200 grams.

Please note that these values are approximate due to rounding during calculations.
