Calculating Molar Mass
Multiple Choice
Which of the following statements is true about the molar mass of chlorine gas?
A
The molar mass of chlorine gas is equal to the sum of the atomic masses of two chlorine atoms.
B
The molar mass of chlorine gas is calculated by dividing the atomic mass of chlorine by two.
C
The molar mass of chlorine gas is the same as the atomic mass of a single chlorine atom.
D
Chlorine gas has a molar mass of approximately 35.5 g/mol.
Verified step by step guidance1
Understand that chlorine gas (Cl\_2) is a diatomic molecule composed of two chlorine atoms bonded together.
Recall that the molar mass of a molecule is the sum of the molar masses of all atoms in the molecule.
Identify the atomic mass of a single chlorine atom, which is approximately 35.5 g/mol.
Calculate the molar mass of chlorine gas by adding the atomic masses of two chlorine atoms: \(\text{Molar mass of Cl}_2 = 2 \times 35.5\ \text{g/mol}\).
Compare this value to the given options to determine which statement correctly describes the molar mass of chlorine gas.
