I believe it is the Great Plains in Nebraska.
The final temperature (°C) of the air at this elevation is 326.3K.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the combined gas law equation as follows:
P₁V₁/T₁ = P₂V₂/T₂
Where;
- P₁ = initial pressure
- V₁ = initial volume
- T₁ = initial temperature
- P₂ = final pressure
- V₂ = final volume
- T₂ = final temperature
According to this question, 1.20L weather balloon on the ground has a temperature of 25.0°C and is at atmospheric pressure (1.00 atm). When it rises to an elevation where the pressure is 0.730 atm, then the new volume is 1.80L. The final temperature can be calculated thus:
1 × 1.2/298 = 0.730 × 1.8/T₂
0.004027T = 1.314
T = 326.3K
Therefore, 326.3K is the final temperature of the balloon.

Moles of NH₃ : = 7.059
<h3>Further explanation</h3>
Given
120 g NH₃
Required
moles NH₃
Solution
The mole is the number of particles contained in a substance
<em>1 mol = 6.02.10²³
</em>
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
So for 120 g (molar mass of NH₃ = 17 g/mol) :
= 120 g : 17 g/mol
= 7.059
