Calculate the Mass of 3.00 Moles of CF2Cl2

To calculate the mass of 3.00 moles of CF₂Cl₂, we first need to determine the molar mass of the compound. CF₂Cl₂ consists of one carbon (C) atom, two fluorine (F) atoms, and two chlorine (Cl) atoms.

Here are the atomic masses of each element:

• C: 12.01 g/mol
• F: 19.00 g/mol
• Cl: 35.45 g/mol

Now we can calculate the molar mass of CF₂Cl₂:

• Molar mass of C = 1 * 12.01 g/mol = 12.01 g/mol
• Molar mass of F = 2 * 19.00 g/mol = 38.00 g/mol
• Molar mass of Cl = 2 * 35.45 g/mol = 70.90 g/mol

Now, adding these together:

Molar mass of CF₂Cl₂ = 12.01 g/mol + 38.00 g/mol + 70.90 g/mol = 120.91 g/mol

Next, to find the mass of 3.00 moles of CF₂Cl₂, we use the formula:

Mass = Number of moles × Molar mass

Substituting the values we have:

Mass = 3.00 moles × 120.91 g/mol = 362.73 g

Thus, the mass of 3.00 moles of CF₂Cl₂ is 362.73 grams.
