How many atoms of sodium are in 0.250 moles of Na2SO4?

Answer 1

in 0.25 moles there are 1.505*10^23 molecules (1 mole of any element=6.023*10^23 molecules)

Answer 2

1 molecule. A molecule is a compound of atleast two atoms, such as H2 (g), O2 (g) or NaBH4 (s) for an example.

Answer 3

0.250 moles Na2SO4 (2 mole Na/1 mole Na2SO4)(6.022 X 1023/1 mole Na)

= 3.01 X 1023 atoms of sodium

======================

Answer 4

The number of nitrogen atoms is 0,752 391411.10e23.

Answer 5

0.25 moles NO2 x 1 mole N/mole NO2 x 6.02x10^23 N atoms/mole N = 1.5x10^23 N atoms

Answer 6

0,25 mole of NO2 gas contain 1,505 535 214 25.10e23 nitrogen atoms.

Answer 7

Approx. 1,5.1023 molecules.

Answer 8

Approx. 1,5.1023 molecules.

Answer 9

This number is 1,5.10e23 molecules.
