Hi I am having trouble in this problem.
What mass of melamine will be obtained from 145.5 kg of urea if the yield of the overall reaction is 81.0%?
First I calculated the number of kilomoles of urea
After I figured out the ratio between urea and melamine
which is 6
Then I figure out the molar mass of melamine
which is 126.0 kg/kmol
This is the part where I get stuck. I cannot figure out the next step to solving this problem.
