does this make sense?
The answer is; A
By using a spring and determining the tension applied on the string by the car, it is possible to deduce the force. Determine the spring's initial tension as well as spring rate and working loads;
Rate = (Load – Initial Tension) ÷ Travel
k = (L – IT) ÷ T
Hey there!!

Hope this helps you and have a great day!!!! I wish you the best of luck (:
Answer:
volume = 2128L
Explanation:
volume at stp = 22.4dm³ =22400L
CO2 = 12 + 2(16) = 44
4.20/44 = volume/22400L
0.095 = volume/22400L
volume = 0.095 x 22400
volume = 2128L
