The two are Celsius and Kelvin. the most used is Kelvin. the reason is that it is more precise measurement.
You have molarity and you have volume. Use the formula :
Molarity(M)= Moles(N)/Liter(L) to get the solution.
150 ml= .150 L
7.7 = N/.150
N=.1.155 moles of NaOH.
And since you know the moles, use the molar mass to figure out the grams.
<span> (40g/mol NaOH) x (1.155mol) =
46.2 g of NaOH.</span>
2355.2 is how many grams there are
Kinetic energy is 1/2m*v^2
They already halved the mass for you and they already squared the velocity for you. I’m unsure why you’re even asking this question. It’s simple multiplication at this point.
(27.5kg)*(4m^2/s^2) = 110 Jules
