Question

calculate the mass of 6.022×10^28 molecules of glucose.​

Answer 1

Answer:

We know that ....

1 mole of atoms = 6.022× 10 ^23 atoms

so 

6.022x10^23 atoms = 1 mole

1 atoms = 6.022×10^23 mole

3.011x10^23 atoms =

=3.011 ×10^23/6.022×10^23

=1/2 mole

and we also know that ....

1 mole of atom = atomic weight

so.

1 mole of glucose.= 342grams

1/2 mole of nitrogen = 1/2x 342=grams

so..mass of nitrogen atom =171 grams..
