Question

calculate the number of atoms in 46g of Na​

Answer 1

Answer:

the number of atoms present in sodium-23 = number of moles of sodium-23 * Avogadro's number.

Answer 2

Answer:

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
