Question

The number of particles in 1 g of a metallic crystal is equal to ____________.

Options

• `1/(ρ"a"^3)`

• `"n"/(ρ"a"^3)`

• `"n"^2/(ρ"a"^3)`

• `("a"^3"N"_"A")/"n"`

Answer 1

The number of particles in 1 g of a metallic crystal is equal to `underline("n"/(ρ"a"^3))`.

Explanation:

The number of particles in 'x' g of a metallic crystal = `("x n")/(ρ"a"^3)`

Therefore, number of particles in 1 g of metallic crystal = `"n"/(ρ"a"^3)`
