Question

The chemical formula for propane is: CH3CH2CH3 Calculate the molar mass of propane. Round your answer to 2 decimal places.

Answer 1

The chemical formula for propane is: CH₃CH₂CH₃, the molar mass of propane is 44.11 g/mol.

Step-by-step explanation:

The molar mass of propane (C₃H₈) can be calculated by adding up the atomic masses of all the atoms in the molecule.

The atomic mass of carbon (C) is 12.01 g/mol, and the atomic mass of hydrogen (H) is 1.01 g/mol.

The molar mass of propane can be calculated as follows:

Molar mass of propane = (3 * atomic mass of carbon) + (8 * atomic mass of hydrogen)

Molar mass of propane = (3 * 12.01) + (8 * 1.01)

Molar mass of propane = 36.03 + 8.08 = 44.11 g/mol

Therefore, the molar mass of propane is 44.11 g/mol.

Answer 2

44.11 g/mol

Step-by-step explanation:

In order to calculate the molar mass of any molecule, we need to add the molar mass of each atom that compounds it:

• Molar Mass of C₃H₈ = (Molar Mass of C) * 3 + (Molar Mass of H)*8

• Molar Mass of C₃H₈ = (12.01) * 3 + (1.01) * 8

• Molar Mass of C₃H₈ = 44.11 g/mol

The molar mass of propane is thus 44.11 g/mol.
