Chapter 28: Problem 9

Calculate the average mass (in amu) of one methane molecule (to \(0.01\) amu).

Short Answer

Expert verified
The average mass of one methane molecule is \(16.05\) amu to the nearest \(0.01\) amu.

Step by step solution

01

Identify the mass of atoms in methane

Methane (CH4) is made up of one carbon (C) atom and four hydrogen (H) atoms. The atomic mass of carbon is 12.01 amu and the atomic mass of hydrogen is 1.01 amu. These atomic masses can be found on the periodic table.
02

Calculate the mass of hydrogen atoms

Since there are four hydrogen atoms in a molecule of methane, multiply the atomic mass of hydrogen by four. Which is, \(4 \times 1.01 = 4.04\) amu.
03

Calculate the total mass of methane

Add the mass of the one carbon atom to the mass of the four hydrogen atoms to find the total mass of the methane molecule. Which is, \(12.01 + 4.04 = 16.05\) amu.
