Solid state: silver density, Chemistry

Assignment Help:

Silver has a density of 10.5gcm-3 . The no. of silver atoms on a surface area of 10-12m2 can be expressed in scientific notation aas y x 10x.The value of x is ..?

Ans) d = mass/V
⇒ 10.5 g/cc means in 1 cc ⇒ 10.5 g of Ag is present.
Number of atoms of Ag in 1 cc ⇒ A
