Question

hen how do u find:

the volume of the H2O released, measured at 220 degrees C and 735mm Hg?
The inital volume is 0.337 grams

Answer 1

I can't make head or tails of the question as it is posted.

Answer 2

Perhaps you want to know the volume of 0.337 g H2O at the P and T of the problem. If so just substitute into PV = nRT
P = 735/760 = ?
T = 220 + 273 = ? K
V = solve for this
n = 0.337/18 = ?
R = 0.08206
Post your work if you stuck.
