AB reacts with C2 to yield AC and B.
2AB+C2 --2AC+2B
The molar mass of AB is 75.0 g/mol, the molar mass of AC is 60.0 g/mol, and the molar mass of B is 50.0 g/mol. What is the theoretical yield (in grams) of AC from the reaction of 29.0 g of AB?

Since the ratio is 2:2 or 1:1, you can tell that the amount of AC you get is the same as the amount of AB you start with. So find the number of moles of AB, then find the mass of AC.

How would I set that up?

wolfe8 · Answer

You find the number of moles of AB first

anonymous · Answer

.387?

wolfe8 · Answer

And like I said, because the ratio is 1:1, that is also the number of moles of AC. So find the mass of AC from that.

anonymous · Answer

Its 60 for AC

wolfe8 · Answer

60 is the molar mass. Mass is number of moles times molar mass.

anonymous · Answer

23.22 would be the answer then?

wolfe8 · Answer

Yup. Good job.

anonymous · Answer

Thank you!! appreciate your help!

wolfe8 · Answer

No problem. Are you new?
