Question: How do you calculate the molecular weight of something like: A_xB_yC where x=1, and y=0.5?
Attempt to the soln:
Let Molecular Weight be MW:
Is it then: MW OF A_xB_yC [x=1, y=0.5] = (MW of A)x1 + (MW of B)x0.5 + (MW of C)? Am I doing this correctly?

No. You have to have whole numbers as subscripts.
A<sub>2</sub>BC<sub>2</sub>
then MW = 2*A+B+2*C
A<sub>2</sub>BC<sub>2</sub>
then MW = 2*A+B+2*C

Even when those individuals elements (A, B and C) were mixed with that composition??

it is the same composition1:.5:1 is the same as 2:1:2 MW reflects the sum of the atomic weights in a MOLE of the substance, not how much you made.
