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

Answer:

$6.022\times 10^{22}molecules$ of dimethylhydrazine are present in 0.100 mol.

Explanation:

Moles of dimethylhydrazine ,n= 0.100 mol

Molecules = Moles × Avogadro number = $n\times N_A$

$N_A=6.022\times 10^{23}$

Number of molecules of  of dimethylhydrazine:

$6.022\times 10^{23}\times 0.100 molecules=6.022\times 10^{22}molecules$

$6.022\times 10^{22}molecules$ of dimethylhydrazine are present in 0.100 mol.
