I am have trouble with doing the calculation for my lab I have a basic idea of what needs to be done, but I think I am confused on how to plug in / use the values that we found.
it was a lab on stochiometry and the reaction of zince and iodine
Iodine was the limiting
Zn: 65.41 g/mole
Iodine:253.8 g/mole
_Zn(s)+_I2(s)-->_ZnI2(s)
trial 1
tube 1 empty weighed: 24.43g
(2.00 g zinc was added and 2.00 iodine)
after recation : 25.92g
25.92g-24.43g=1.49g mass of remaining zinc
250mL beaker empty with chip: 106.92g
after: 109.29g
109.29g-106.92g=2.37g mass of zinc iodiede produce
trial 2
tube 2 empty:33.42 g
(1.7 g iodine and 2.00g zinc)
after: 34.98g zinc remaing
34.98g-33.42g=1.56g zinc remaing
trial 3
tube 3 empty: 24.42g
( 1.40g iodine and 2.00 zinc)
after :26.06g
26.06g-24.42g=1.64g of zinc remaing
I need help finding Moles of reacted Iodine, moles of reacted zinc, and the molar ration of reacted Zn:I2 for each trial.
then I know I take the average I need to then find the coefficients for the chemical equation which I am not sure if I undertand how to do that with the average.
I also need to figure out the percent yield of zinc iodiede
then for trial 1 i need the mass of zinc consumed
mass of iodine consumed and
the mass of Zinc iodided consumed
I am just super stuck on how to take what i have and plug it in
