How many atoms are present in 41.23 grams of sodium?

Answer 1

molar mass of sodium = 23

number of mols = mass/ molar mass

therefore 46g of Na = 2 mol

Answer 2

To find the number of atoms in 41.23 grams of sodium, you first need to convert the grams to moles using the molar mass of sodium. The molar mass of sodium is approximately 22.99 g/mol. Next, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms. This will give you the number of atoms present in 41.23 grams of sodium.

Answer 3

Amount of Na = 41.23/23.0 = 1.79mol

1 mol of Na contains 6.02 x 1023 atoms (avogadro constant).

Number of Na atoms = 1.79 x 6.02 x 1023 = 1.08 x 1024

Answer 4

The total number of sodium atoms in 46,0 grams of sodium is 12,044 280.10e23.

Answer 5

12.04 x 10^23

Answer 6

62 grams
