Question

Moles in 46g of na atoms?

Answer 1

Hello..

Here you go..

a)46g of Na atom

atomic mass of Na=23u

Number of particles=Number of Moles x N

⇒(given weight/ Gram atomic weight) x 6.023 x 10²³

=(46/23)x 6.023 x 10²³

=2x 6.023 x 10²³

⇒12.046 x 10 ²³Na particles

∴46 g of Na contains 12.044 x 10 ²³

Hope it helps..
