@@jasminenikzai2238 since he had already input the the numbers he knew into the equation (deltaTsubF=0.543 and Ksubf=a known constant that he had handy on him) all he had left was to solve for the molality=m. To get the "m" by itself he divided 1.86 from both sides and got 0.292 = m.
You did in 3 and a half minutes what a whole bunch of other youtubers couldn't do in 15-20 minutes you're a God send thank you so much
Thank you so much. Questions like these give me a hard time and I find them confusing but you just helped me understand.
thank you. i love your videos. you're great at explaining each step which is really helpful!
A way of good 👍 explanation
thank you so much
Can you explain where you got 0.292 mol from?
exactly what I’m confused on as well
@@Thebestcoldkilla literally same.. he didn't even explain

How did you get 1.86?
1.86 is the constant Kf value for water - so it's just a given constant for water.
How did he find the value of Kf?
constant value of water in Kf
