Composition of an Alloy: A Creative Exploration

How can we determine the composition of an alloy based on weight percentage?

Given an alloy consisting of 6 at% Pb and 94 at% Sn, how can we calculate the composition in weight percent?

Answer:

The composition of an alloy can be determined by calculating the weight percentage of each component in the alloy. In this case, the alloy consists of 6 at% Pb and 94 at% Sn.

Composition of alloys can be determined using weight percentages. The weight percentage of each component in an alloy can be calculated by dividing the mass of each component by the total mass of the alloy and multiplying by 100%.

Steps to Determine the Composition of the Alloy:

Step 1: Calculate the atomic weight of each element involved in the alloy.

Pb (lead) = 207.2

Sn (tin) = 118.7

Step 2: Calculate the mass of each element.

Mass of Pb = 0.06 x 207.2 = 12.43

Mass of Sn = 0.94 x 118.7 = 111.698

Step 3: Calculate the total mass of the alloy.

Total mass of the alloy = 12.43 + 111.698 = 124.128 g

Step 4: Calculate the weight percentage of each element.

Weight percentage of Pb = (12.43 / 124.128) x 100% = 10.01%

Weight percentage of Sn = (111.698 / 124.128) x 100% = 89.99%

Therefore, the composition of the alloy is 10.01% Pb and 89.99% Sn.
