Answer 2

Calculating the Molar Mass of Dichloromethane

To calculate the molar mass of dichloromethane, we need to consider the atomic masses of the elements present in the compound and their respective quantities.

Dichloromethane has the chemical formula CH2Cl2. To calculate its molar mass, we can use the atomic masses of carbon (C), hydrogen (H), and chlorine (Cl) from the periodic table.

The atomic masses are as follows: - Carbon (C): 12.01 g/mol - Hydrogen (H): 1.008 g/mol - Chlorine (Cl): 35.45 g/mol

Now, we can calculate the molar mass of dichloromethane using the formula: Molar mass = (number of carbon atoms * atomic mass of carbon) + (number of hydrogen atoms * atomic mass of hydrogen) + (number of chlorine atoms * atomic mass of chlorine)

For dichloromethane (CH2Cl2): Molar mass = (1 * 12.01) + (2 * 1.008) + (2 * 35.45)

Molar mass of dichloromethane = 12.01 + 2.016 + 70.90 Molar mass of dichloromethane ≈ 84.986 g/mol Therefore, the molar mass of dichloromethane is approximately 84.986 grams per mole.
