Calculating Molar Mass
Multiple Choice
Which of the following is the molar mass of carbon (C)?
A
14.01 g/mol
B
16.00 g/mol
C
12.01 g/mol
D
1.01 g/mol
0 Comments
Verified step by step guidance1
Understand that the molar mass of an element is the mass of one mole of its atoms, usually expressed in grams per mole (g/mol).
Recall that the molar mass of carbon (C) corresponds to the average atomic mass of carbon atoms found on the periodic table.
Look up the atomic mass of carbon on the periodic table, which is approximately 12.01 atomic mass units (amu).
Since 1 mole of carbon atoms has a mass equal to the atomic mass in grams, the molar mass of carbon is 12.01 g/mol.
Compare the given options to identify that 12.01 g/mol matches the molar mass of carbon.
