How many atoms are present in 200.g of glucose c^6 h^12 o^6

Mass of each atom of carbon = 12

No of carbon atom = 6

Total mass of carbon atom = 12 X 6 = 72

Mass of each atom of hydrogen = 1

No of hydrogen atom = 12

Total mass of hydrogen atom = 1 X 12 = 12

Mass of each atom of oxygen = 16

No of oxygen atom = 6

Total mass of oxygen atom = 16 X 6 = 180

Total: 180 g / mole glucose

No of atoms = 200 g glucose / 180 g/mole glucose * 6.022 X 10^23 molecules glucose/mole glucose * 24 atoms/molecule glucose

= 16.044 X 10^24 atoms are present in 200 grams of glucose

Hope it helps!!!

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
