Answer : The reaction requires 242 grams of HF.
Explanation : Given,
Mass of = 182 g
Molar mass of = 60 g/mole
Molar mass of HF = 20 g/mole
First we have to calculate the moles of
Now we have to calculate the moles of HF.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 1 mole of react with 4 moles of HF
So, 3.03 moles of react with moles of HF
Now we have to calculate the mass of HF.
Therefore, the reaction requires 242 grams of HF.

Explanation:
Hello,
In this case, considering that the valve is opened, we can use the Boyle's law in order to compute the final pressure of argon by considering its initial pressure and volume and a final volume of 5.0 L:
And the final pressure of helium:
Which actually are the partial pressure of both of them, it means that the total pressure is:
Finally, the mole fraction of each gas is computed by considering the Dalton's law:
Best regards.
