Methane is CH4. } The periodic table lists the atomic mass of carbon as 12.011 amu; the average molar mass of carbonthe mass of 6.022 1023 carbon atomsis therefore 12.011 g/mol: The molar mass of naturally occurring carbon is different from that of carbon-12 and is not an integer because carbon occurs as a mixture of carbon-12, carbon-13, and carbon-14. B Taking the atomic masses from the periodic table, we obtain, \( 2 \times atomic;\ mass\;of\:carbon = 2\;atoms \left( {\dfrac{12.011amu}{atom}} \right) = 24.022\;amu\), \( 6 \times atomic;\ mass\;of\:hydrogen = 6\;atoms \left( {\dfrac{1.0079amu}{atom}} \right) = 6.0474\;amu\), \( 1 \times atomic;\ mass\;of\:oxygen = 1\;atoms \left( {\dfrac{15.9994amu}{atom}} \right) = 15.9994amu\).
