First of all, lets get our equation for Kinetic Energy (KE).
KE = 1/2 (mass) (speed)2
<span>Now, replace the words by adding the actual values. </span>
KE = 1/2(2 kg) x (45 m/s)^2
KE = 2025 J
Answer: Kinetic energy = 2025 Joules
Acetic acid is 60.05 grams/mole. In 1 liter of vinegar or 1000 ml there would be 0.046% of acetic acid = 46 ml x 1.005g/ml = 46.23 grams/60.05 grams= 0.77 moles per litre of vinegar.This then would be the concentration of acetic acid in for example 1 liter of vinegar.
