Question

Find out mass of 12.044 x 10^24 atoms of magnesium.​

Answer 1

Answer:

480 gm

Explanation:

we know that 1 mole of Mg weighs 24 gm

also 1 mole of Mg has 6.022*10^23 particles

ie Avagadro number of particles

therefore 12.044*10^24 has

=12.044*10^24*1/6.022*10^23

=20 moles

therefore mass of 20 moles is

24*20

=480 gm

Hope this helps.

Answer 2

Answer:

Explanation:

the mass of 1 atom of mg = 24/6.023 * 10⁻²³

or the mass of 12.044*10⁻²³ atoms will be 12.044 * 10⁻²³ X (24/6.023X10⁻²³)

gms = 2*24gms

the mass is 48gms
