**Question 22: What is the mass in grams of each of the following?** a. \(3.011 \times 10^{23}\) atoms F b. \(1.50 \times 10^{23}\) atoms Mg c. \(4.50 \times 10^{12}\) atoms Cl d. \(8.42 \times 10^{18}\) atoms Br e. 25 atoms W f. 1 atom Au --- To convert the number of atoms to grams, use the formula: \[ \text{Mass (g)} = \left(\frac{\text{Number of Atoms}}{\text{Avogadro's Number}}\right) \times \text{Molar Mass (g/mol)} \] Where Avogadro's Number is \(6.022 \times 10^{23}\) atoms/mol. You will need the molar mass of each element: - Fluorine (F): approximately 19 g/mol - Magnesium (Mg): approximately 24.305 g/mol - Chlorine (Cl): approximately 35.453 g/mol - Bromine (Br): approximately 79.904 g/mol - Tungsten (W): approximately 183.84 g/mol - Gold (Au): approximately 196.967 g/mol Calculate the mass for each part using the formula provided.
