What is molecular weight (mass?

Carbon has an atomic number of 6 and a mass number of 12. hydrogen has an atomic and mass number of 1. oxygen has an atomic number of 8 and a mass number of 16. what is the molecular weight of glucose (c6 h12 o6)? 29amu, 96amu, 180amu, 252amu, 432 amu

  • Answer:

    It is 180 amu. That is, c6h12o6= (6*12)+(1*12)+(6*16)=180.

TO FIND THE MOLECULAR WEIGHT OF GLUCOSE: (1)MULTIPLY 6 WITH THE ATOMIC MASS OF CARBON (2)MULTIPLY 12 WITH THE ATOMIC MASS OF HYDROGEN (3)MULTIPLY 6 WITH THE ATOMIC MASS OF OXYGEN (4)THEN ADD ALL OF THEM YOU WILL GET LIKE THIS:6*12=72 12*1=12 6*16=96 HENCE MOLECULAR FORMULA FOR GLUCOSE WILL BE: 72+12+96=180
