The molar mass of butane,C 4 H 10 ,is ________ grams.

To find the molar mass of butane, we add up the atomic masses of all the atoms in the molecule. C = 12.01 g/mol x 4 = 48.04 g/mol H = 1.01 g/mol x 10 = 10.10 g/mol Total molar mass = 48.04 g/mol + 10.10 g/mol = 58.14 g/mol Therefore, the closest answer is D) 58.12 g/mol.
