Answer

Using the formula and substituting these values in, we get . So, the mass percentage of Magnesium (Mg) in is approximately 20.25%.

Explanation

## Step 1:The first step to solve this problem is to understand the concept of percent composition by mass. It is the percentage by weight of a particular element in a compound. The formula to calculate this is:### ## Step 2:In this problem, we are asked to find the percent composition by mass of magnesium (Mg) in the compound . The atomic mass of magnesium (Mg) is approximately 24.3 g/mol, which can be found in the periodic table. ## Step 3:We are given that the molar mass (also known as gram formula mass) of the entire compound is 120 g/mol. ## Step 4:Substitute these values into the formula from Step 1 to find the percent composition by mass of magnesium in .
