assume a liter of beer...
Molarity=molesalcho/1
but mass alcohol=.046*.93*1000= you do it.
Molarity=massalcohol/MolmassC2H5OH
and there you have it.
Molarity=molesalcho/1
but mass alcohol=.046*.93*1000= you do it.
Molarity=massalcohol/MolmassC2H5OH
and there you have it.

So the answer is:
43.78 / 46.068 = 0.929 M?
43.78 / 46.068 = 0.929 M?

recheck your mass alcohol...
.046*.93*1000= in your google search window
.046*.93*1000= in your google search window
