Question
Calculate the mass (in g) of two moles of chlorine molecules (Cl2). M Cl = 35.45 g mol–1
Solution
Sure, here's how you can calculate the mass of two moles of chlorine molecules (Cl2):
Step 1: Determine the molar mass of Cl2. Since a molecule of Cl2 consists of two chlorine atoms, you would multiply the molar mass of a single chlorine atom by 2.
Molar mass of Cl2 = 2 * Molar mass of Cl = 2 * 35.45 g/mol = 70.9 g/mol
Step 2: Multiply the molar mass of Cl2 by the number of moles to get the mass.
Mass = Molar mass * number of moles = 70.9 g/mol * 2 mol = 141.8 g
So, the mass of two moles of chlorine molecules (Cl2) is 141.8 grams.
