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

#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
