Question

calculate the number of moles present in 180 gm of glucose ​

Answer 1

Given:-

→Mass of glucose = 180g

To find:-

→Number of moles in 180g of glucose

Solution:-

Chemical formula of glucose:-

=>C₆H₁₂O₆

Thus,three elements are present in glucose i.e. Carbon,Hydrogen and Oxygen

•Atomic mass of Carbon = 12u

•Atomic mass of Hydrogen = 1u

•Atomic mass of Oxygen = 16u

Thus,molecular mass of glucose:-

=>12(6)+1(12)+16(6)

=>72+12+96

=>180u

∵Molecular mass of glucose is 180u

∴Molar mass of glucose is 180g.

Now,number of moles:-

=>Given Mass/Molar mass

=>180/180

=>1 mole

Thus, 1 mole is present in 180g of glucose.
