Question

e) If 1 g carbon contains x atoms, what will be the number of atoms in 1
g of water?​

Answer 1

Answer:

Given:

1 g of carbon contains x atoms ......... (1)

1 mole of carbon = gram molecular mass of carbon = 12 gms

i.e., 12 gms of Carbon = 1 mole

therefore comma space 1 space gm space of space carbon space equals space 1 over 12 space moles ...........(2)

From (1) and (2) we get,

therefore comma space 1 space gm space of space carbon space equals space 1 over 12 space moles space equals space straight x space space atoms

As given we have to find out the number of atoms in 1 gm of Mg,

1 mole of Mg = 24 gm ..... ( mass no. of Mg = 24)

therefore comma space 1 space gm space of space space Magnesium space equals space 1 over 24 space moles ...... (3)

In order to find the number of atoms of Mg in 1 g, lets solve (2) and (3)
