A liquid has a maximum density of 0.6 g/cm^3 at 3.7 C. At 11.4C , its density is 0.60888 g/cm^3. What is beta for this liquid over this temperature interval? Answer in units of (C)^-1.

Obviously this has to do with the volume expansion so I made the formula deltaV = beta * initial volume * delta temperature into beta = deltaV / (initial volume * delta temperature) assuming that initial volume is 1 cm since its not stated in the problem and thats wrong.

I came out with 0.00115325 doing it that way. System says I am wrong.

Am I on the right track or am I not thinking outside the box enough?

Hmm....switching to kelvin opps

edit: doesn't matter since its a constant.

Is 0.60888 less than, equal to, or greater than 0.6? Methinks you need to check the question, and if you've copied it correctly, it's time to pick bones with whoever programs the exercises into the "system."
