Answer 2

Calculating Percentage of Silver in the Alloy

To calculate the percentage of silver in the alloy, we can use the following formula:

Percentage of silver = (Mass of silver / Total mass of alloy) * 100

Given: - Mass of the alloy = 180 g - Mass of silver in the alloy = 72 g

Using the formula: Percentage of silver = (72 g / 180 g) * 100

Calculation

Percentage of silver = (72 / 180) * 100 = 40%

Therefore, the alloy contains 40% silver.
