Question

How would you find the mass of a temperature of water, given volume and the density of another temperature of water?

Answer 1

you can't because they dont have a linear relationship..

However, you can use a \(\sf density ~vs~ temperature~ graph\)
(like this one http://hypertextbook.com/facts/2007/AllenMa.shtml)

and extrapolate the density at a given temperature, AND use the volume you were given to find the mass.
