Question

Plz someone solve and send me the answers of these..​

Answer 1

Explanation:

hence last option has highest no. of atom

Answer 2

Explanation:

N =6.023×10^23

1 mole of gold= N atoms of goldN at

33 moles of gold=33N atoms of gold

in case of calcium,

40g = 1mole=N atoms

454g= N/40*454 atoms

= 11.34 N atoms

in case of Neon,

20g = N atoms

322g=322N/20 atoms

in case of lithium,

1 mole= N atoms

524 moles= 524N atoms

in case of N2

28g=1 mole=N molecules=2N atoms

222g= 222*2N/28 atoms

1mole Fe= N atoms

22.10*10^22 mole= 22.10*10^22Natoms
