Chemistry Problem, Help!!
Ok i have this Chem. problem it sound easy but for some reason i can't get it, it says:
A flask holds a total of 402.5 Grams of water at 293.4 K. What is the volume of the flask?!
P.S. using the Ideal gas law PV=nRT would result in a big unrealistic #.
if you gonna try to convert the 402.5 Grams to moles then here is the molar mass for the water 18.02 g/mol.
thanx in advace

LOL...I couldn't do that for you now if I tried....Fvkkin Horny Goat Weed.

1g is by definition the amount that 1 cubic centimeter of water weighs. your flask is 402.5mL
EDIT: curiously, why were you using the ideal gas law for liquid water?

actually no, at ~20C not 4C so its 0.9982g/ml
so it would be 401.8ml
small, but enough to get the problem wrong

I stand corrected

yea, what syma said

thats actualy why water is so special, its density is highest at 4C where as most liquids density increases with temp decrease to a solid max
thats why ice floats
good thing or we would have like frozen oceans and shit and it would be a mess
