What is Hydrofluoric acid?</h3>
A hydrogen fluoride and water solution is hydrofluoric acid. HF solutions are colorless, corrosive, and acidic. The majority of fluorine-containing chemicals are made using it; examples include the substance PTFE and the widely used psychiatric drug fluoxetine. Aluminum, plastics, electrical components, pharmaceuticals, high-octane fuel, fluorescent light bulbs, and refrigerants are all made with hydrogen fluoride. The production of refrigerants uses 60% of the hydrogen fluoride used in manufacturing. corrosive due to the acid's H+ ions and poisonous due to the fluoride ions F-, which can penetrate deeply, chelate calcium and magnesium, and thus upset biological balances due to the destruction of the skin's or an eye's outermost layer.

Answer:- 475 mL.
Solution:- It's based on Boyle's gas law. At constant temperature, "The volume of the gas is inversely proportional to the pressure."
Equation for this law is written as:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
P and V stands for pressure and volume where as the subscripts 1 and 2 are for initial and final values.
Initial pressure is 6.20 atm and it asks to calculate the initial volume. Final pressure is 9.150 atm and the final volume is 322 mL.
Let's plug in the values in the equation and solve it for initial volume:
![6.20atm(V_1)=9.150atm(322mL)](https://tex.z-dn.net/?f=6.20atm%28V_1%29%3D9.150atm%28322mL%29)
On dividing both sides by 6.20 atm:
![V_1=\frac{9.150atm(322mL)}{6.20atm}](https://tex.z-dn.net/?f=V_1%3D%5Cfrac%7B9.150atm%28322mL%29%7D%7B6.20atm%7D)
= 475 mL
So, the originally the gas container volume was 475 mL.
The correct answer to this question would be heat energy
