The balance chemical equation is
2N2 + O2 ---> 2N2O.
We can solve how many moles of nitrous oxide gas from 1.65 moles of nitrogen gas. The balance equation is a critical information to answer this problem since it gives the ratio of nitrous oxide gas produced to the nitrogen used. 2 moles of nitrous oxide gas is produced from 2 moles of nitrogen gas is used. Hence there is 3.30 moles of nitrous oxide gas produced.

Answer:
1.4e+8 bismuth atoms
Explanation:
If 10³ mm = 10¹² pm
then 44 mm = X pm
X = (44 × 10¹²) / 10³ = 44 × 10⁹ pm (which is the cookie diameter in picometers)
Now we can calculate the number of bismuth atoms needed to span the diameter of the cookie:
number of bismuth atoms = cookie diameter / bismuth atom diameter
number of bismuth atoms = 44 × 10⁹ / 320 = 0.1375 × 10⁹ atoms = 1.375 × 10⁸ atoms
And now to respect the answer format requested by the problem:
1.375 × 10⁸ = 1.375e+8 ≈ 1.4e+8
