For the following compound, calculate the molar mass: CH4Example: CHCl3 = 119.38 amu

Sagot :

• The mass of carbon is 12.0107 amu.

,

• The mass of Hydrogen is 1.0078 amu.

Before we add the masses above, we have to multiply the mass of one Hydrogen atom by 4 because in the compound CH4 there are 4 hydrogens atoms.

[tex]4\cdot(1.0078amu)=4.0312amu[/tex]

Them, we add the masses.

[tex]12.0107\text{amu}+4.0312\text{amu}=16.0419amu[/tex]

Therefore, the mass of the compound is 16.04 amu.
