Answer :
C8H12O6 ==>
6C * 12.011g/mol = 72.066g/mol
12H * 1.0079g/mol = 12.0948g/mol
6O * 15.9994g/mol = 95.9964 g/mol
72.066g/mol + 12.0948g/mole + 95.9964 g/mol
= 180.1572 g/mol
C8H12O6 ==>
6C * 12.011g/mol = 72.066g/mol
12H * 1.0079g/mol = 12.0948g/mol
6O * 15.9994g/mol = 95.9964 g/mol
72.066g/mol + 12.0948g/mole + 95.9964 g/mol
= 180.1572 g/mol
