How many atoms are in 3.47 moles of C2H2? Please show work.

2.08×10^24 atoms

Explanation:

set up a mole to atom ratio:

3.47moles 1 mole

=

x atoms 6.02×10^23 atoms

cross multiply:

3.47 mole × 6.02 × 10^23 = 2.08×10^24 atoms

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
