Answer: R: 29.4, G: 0, B: 51, or #3F00FF.
The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

I am aware this is a multiple choice question. There is only one answer.
Hey there! :)
Your answer is mean
_____________________________________________________________
Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.
Finding the mode is pretty useless because you can't do much with the score that you got the most.
Range isn't that helpful because it's the difference between your best and worst score.
Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________
Therefore, the answer is mean
Hope this helps :)
