The volume of an object is 4 cubic centimeter and mass of an object is 104 gram. What is the density of the object?

Answer»

Answer:

GIVEN density =1×10

kgm

−3

=1 gm

−3

MOLAR mass of water =18 gm/mole

No. of moles in 1 gm =1/18=0.55 moles

18 gm contain MOLECULES of H

O = 6.022×10

1 gm contain molecules of H

O =

6.022×10

=0.33×10

Volume occupied by 1 molecule of water is =

0.33×10

=2.99×10

−23
