I have researched that isobutanol has a heat of combustion of 35981 kJ/kg; however I need this to be in kJ/mol. From calculations, the molar mass of isobutanol was found to be 74g/mol. How would I go about in converting this?
Relevant equations (?)
#mols=mass/molarmass
But how can I use this?
Hi,
I've done a prac at school where we had to take an accelerometer onto a ride and obtain a graph in at duration. However, the data I've obtained (Acceleration in X, Y Z and resultant) is experimental data. I need to calculate theoretical data for certain segments of the ride. Assuming that I...
Ah I see! I completely forgot that v=d/t can still be used to calculate the horizontal component of the velocity! With that, I can calculate the initial velocity easily! Thankyou so much for your help!:smile:
Oops, I am very sorry about that. I am aware of the 4 kinematic equations, however, won't using those only give me the average velocity instead of the instantaneous velocity? Perhaps I should explain the task in a better, more detailed way:
The task was to create a projectile launcher (I...
Hi all,
I have been given a projectile motion problem, where a ball is launched from a catapult. The range, maximum height and the launching angle is known. The range is 2.32m, the max. height is 1.26m and the launching angle is 35° from the horizontal. The projectile flight goes for 1.125...
