D phenolphthalein is the answer
P1V1 = P2V2
P1 = 0.60 atm
V1 = 10.2 L
P2 = ?
V2 = 3.0 L
Solve for P2 —> P2 = P1V1/V2 = (0.60 atm)(10.2 L) / (3.0 L) = 2.04 atm
Yes it is possible because, olymorphismis when two or more crystal structures are possible for a material of given composition. Isomerismis when two or more polymer molecules or repeat units have the same composition, but different atomic arrangements.
Okay, to do this you have to work with the relative molecular mass (RMM). You can get this from looking at the periodic table.
The RMM for the whole molecule is:
58.933 + (2 x 35.453) + (12 x 1.008) + (6 x 15.9994) = 237.96
Then you work out the RMM for water:
(2 x 1.008) + 15.9994 = 18.0154
As there are 6 moles of water in this molecule then multiply the RMM of H2O by 6 = 108.0924
Finally, divide the total H2O RMM by the total molecule RMM and multiply by 100 to get a percentage:
(108.0925 / 237.96) x 100 = 45.42%
