Calculate the molecular mass of glucose ...

Calculate the molecular mass of glucose `(C_(6)H_(12)O_(6))` molecule in amu.

Text Solution

Verified by Experts

Molecular mass of glucose `(C_(6)H_(12)O_(6))=6(12.011" amu")+12(1.008" amu")+6(16.00" amu")`
`=72.066" amu"+12.096" amu"+96.000" amu"=180.162" amu."`
