Answer:

Step-by-step explanation:

Glucose has 6 number of carbon atoms, 12 atoms of oxygen and 6 atoms of oxygen

The total number of glucose atom is 24 atoms

The atom of hydrogen is twice that of carbon

that is (6.02 x10^22) x2=1.204 x10^23atoms

the number of moles of hydrogen is solved as follows

1mole = 6.02x10^23 atoms what about 1.204 x10^23=

{(1.204x10^23)/(6.02 x10^23)}=0.2moles

The moles of glucose

1 atom of glucose= 6.02 x10^22 x4 =2.408 x10^23 atoms

moles= { (2.48 x10^23)/(6.02 x10^23)}=0.41moles

Hope this helped :)
