Answer 2

Calculation of Alloy Mass

To find the mass of the alloy, we can use the given ratio of lead to antimony in the alloy and the mass of lead present.

Given: - Mass of lead in the alloy = 272 kg - Ratio of lead to antimony = 3:17

Solution

First, we need to find the mass of antimony in the alloy.

Let's denote: - Mass of lead = L - Mass of antimony = A

According to the given ratio, we have: - L = (3/20) * (L + A) - A = (17/20) * (L + A)

We know that the mass of lead in the alloy is 272 kg. Using this information, we can solve for the mass of the alloy.

Calculation

We can use the given mass of lead to find the mass of antimony in the alloy.

The mass of antimony (A) can be calculated as follows: - A = (17/20) * (272 kg + A)

Solving for A: - A = (17/20) * 272 kg + (17/20) * A - A - (17/20) * A = (17/20) * 272 kg - (20/20 - 17/20) * A = (17/20) * 272 kg - (3/20) * A = (17/20) * 272 kg - A = (17/3) * 272 kg

Result

The mass of the alloy can be found by adding the mass of lead and the mass of antimony: - Mass of alloy = Mass of lead + Mass of antimony - Mass of alloy = 272 kg + (17/3) * 272 kg - Mass of alloy = 272 kg + 1544 kg - Mass of alloy = 1816 kg

Therefore, the mass of the alloy is 1816 kg.
