aaronq · Answer

add the moles, divide by the total (both volumes) volume

anonymous · Answer

is there any formula to know (besides how to add) or that's just the way to do it?

aaronq · Answer

nope, no direct formula

aaronq · Answer

There's more to being a chemist, rather than just applying formulas :P

aaronq · Answer

other** damn autocorrect

anonymous · Answer

Haha, aaah. I did add the moles ( .150 + .400 = .550) and then volumes (50 + 25 = 75) and divided and got a weird answer, unless i did it wrong
