Question #edc86

Answer 1

See explanation.

Explanation:

In `6.03` moles of `C_2H_2` there are:

`6.03xxN_A=6.03xx6.022xx10^23=3.63xx10^24` particles of `C_2H_2`.

Every particle has 2 atoms of hydrogen, so there are `7.26xx10^24` atoms of hydrogen in tthe sample.

`N_A=6.022xx10^23` is Avogadro's number - the number of particles in 1 mole of a substance

Answer 2

`7.26*10^24`

Explanation:

`6.03 mol (C_2H_2) * (2 mol (H))/(1 mol (C_2H_2)) = 12.06 mol (H)`

`12.06 mol (H) * 6.022*10^23=7.26*10^24` atoms of hydrogen
