Question

Given the atomic weights of carbon, 12.01; hydrogen, 1.01; and oxygen, 16.0, what is the molar mass of glucose (C6H12O6)? A. 166.18 grams B. 174.12 grams C. 180.18 grams D. 250.12 grams

Answer 1

Glucose has the formula: C6H12O6

so

12.01 x 6

1.01 x 12

16 x 6

gives us: 180.18 gm

Answer 2

Glucose consist of 6 molecules of carbon, 12molecules of Hydrogen and 6molecules of oxygen.

So if the molecular mass of 1 carbon in 12.01grms then for six molecules the weight will be 6*12.01 which is=72.02grms.

Similarly,

• weight of Hydrogen in glucose will be 12*1.01 =12.12grms

• weight of oxygen in glucose=) 6*16=96grms

Therefore the weight of the glucose will be the sum of above.
