Question

calculate the mass of magnesium that contains same number of atoms as that is 16 gram of sulphur​

Answer 1

16 g of sulphur makes upto 0.5 moles of sulphur bcoz you divide 16 by its mol wt which is 32g..

thus equal moles contain equal molecules according to avogadro's hypothesis.

so number of moles of mg=0.5

thus to get its weight, multiply 0.5 by mol wt of mg.

=0.5*24 = 12g.

Answer 2

Number of atoms/ 6.022*10^23=

Mass in gram/ gram atomic Mass

X/6.022×10^23=16/32

X= 3.011×10^23

Number of atoms/ 6.022*10^23=

Mass in gram/ gram atomic Mass

3.011×10^23/6.022*10^23=Y/24

Y=12
