Calculating Molar Mass of Methane
Methodology for Calculating Molar Mass
The molar mass of methane can be calculated by summing the atomic masses of its constituent atoms. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of hydrogen is approximately 1.01 g/mol.
The molar mass of methane (CH4) can be calculated by adding the atomic masses of its constituent elements, which are carbon (C) and hydrogen (H). The atomic masses are as follows:
Carbon (C): 12.011 g/mol
Hydrogen (H): 1.008 g/mol
Since there is one carbon atom and four hydrogen atoms in one molecule of methane, the molar mass can be calculated as:
(1 * atomic mass of carbon) + (4 * atomic mass of hydrogen)
= (1 * 12.011 g/mol) + (4 * 1.008 g/mol)
= 12.011 g/mol + 4.032 g/mol
= 16.043 g/mol
Therefore, the molar mass of methane (CH4) is approximately 16.043 grams per mole.
Breaking Down the Calculation Step by Step
To calculate the molar mass of methane, multiply the atomic mass of carbon by one and the atomic mass of hydrogen by four, then add the results together. The molar mass of methane is approximately 16.04 g/mol.
Examples of Calculating Methane’s Molar Mass
For example, the molar mass of methane can be calculated using the formula:
Molar Mass (CH4) = (1 x 12.01 g/mol) + (4 x 1.01 g/mol) = 16.04 g/mol.
