27 km = 27000m. Time = distance/speed = 27000/3x10^8 = 9x10^-5 s.
Electrical energy is converted to waste heat. I’m not sure but this is what I think...
Answer:
The answer is "11.07 g".
Explanation:
Isoamyl alcohol is a reagent restriction
Isoamyl alcohol Moles:

Moles only with the shape of isoamyl acetate are equivalent to numbers.
Isoamyl acetate grams:

<h3>
<u>moles of H2SO4</u></h3>
Avogadro's number (6.022 × 1023) is defined as the number of atoms, molecules, or "units of anything" that are in a mole of that thing. So to find the number of moles in 3.4 x 1023 molecules of H2SO4, divide by 6.022 × 1023 molecules/mole and you get 0.5646 moles but there are only 2 sig figs in the given so we need to round to 2 sig figs. There are 0.56 moles in 3.4 x 1023 molecules of H2SO4
Note the way this works is to make sure the units are going to give us moles. To check, we do division of the units just like we were dividing two fractions:
(molecules of H2SO4) = (molecules of H2SO4)/1 and so we have 3.4 x 1023/6.022 × 1023 [(molecules of H2SO4)/1]/[(molecules of H2SO4)/(moles of H2SO4)]. Now, invert the denominator and multiply:

Answer:
Mole of the H2O = 4.5
Number of molecules =4.5 multipled by avogadro's number.
