Question

0. In 0.100 mole of dimethylhydrazine, (CH3)2N2H2, there are A. 6.02 x 1023 molecules B. 6.02 x 1024 molecules C. 7.22 x 1023 atoms D. 6.62 x 1023 atoms E. 4.82 x 1023 atoms

Answer 1

`6.022* 10^(22)molecules` of dimethylhydrazine are present in 0.100 mol.

Step-by-step explanation:

Moles of dimethylhydrazine ,n= 0.100 mol

Molecules = Moles × Avogadro number =
`n* N_A`

`N_A=6.022* 10^(23)`

Number of molecules of of dimethylhydrazine:

`6.022* 10^(23)* 0.100 molecules=6.022* 10^(22)molecules`

`6.022* 10^(22)molecules` of dimethylhydrazine are present in 0.100 mol.
