Question

during respiration a six carbon molecule glucose (c6h12o6) undergoes combustion. calculate its molar mass

Answer 1

To calculate Molar mass of glucose (C6H12O6) we need to separately determine molar masses of elements which form glucose.
Molar mass of carbon is 12 as 6 atoms of carbon are there so 6×12=72
Molar mass of hydrogen atom is 1.008 and 12 atoms are there so 1.008×12=12.096
Molar mass of oxygen atom is 16 as 6 atoms are there so 16×6=96
So molar mass of glucose will be sium of these which is 72+12.096+96=180.096

Answer 2

To calculate the molar mass of Glucose -C6H1206
Atomic mass of C=12U
Atomic mass of H=1.008u
Atomic mass of oxygen=16u
so molecular mass of glucose=Sum of all the atomic masses of atoms
=6x12+12x1.008+6x16
=72+12.008+96
=180.096u
∴ molar mass of C6H12O6=180.096g
