Answer:
The atomic mass of carbon (C) is 12.0107 amu, so if you want to calculate the total mass in each molecule, you just need to multiply the number of carbon atoms in the substance by 12.017. In (a) there is one atom of C, (b) have also one atom of C, (c) have 12 atoms of C, and (d) have five atoms of C. Thus, the total mass (amu) of carbon is:
(a) 12.017 amu
(b) 12.017 amu
(c) 144.204 amu
(d) 60.085 amu
The mass of carbon in [tex]\rm CH_4[/tex] is 12.007 amu, [tex]\rm CHCl_3[/tex] is 12.007, [tex]\rm C_1_2H_1_0O_1_6[/tex] is 144.084 amu, and [tex]\rm CH_3CH_2CH_2CH_2CH_3[/tex] is 60.035 amu.
The mass has been given as the sum of the atomic mass unit in the compound. The mass of 1 atom of carbon is 12.007 amu.
The mass of carbon in the following compounds is given as:
The number of Carbon units = 1
The mass of carbon in compound = 12.007 amu
The number of Carbon units = 1
The mass of carbon in the compound = 12.007 amu
The number of carbon units =12
The mass of carbon in the compound:
[tex]\rm 12\;\times\;12.007\;amu\\=144.084\;amu[/tex]
The number of carbon units = 5
The mass of carbon in the compound:
[tex]\rm 5\;\times\;12.007\;amu\\=60.035\;amu[/tex]
