A hydrated blue copper(II) sulfate salt with a formula YCuSO4•XH2O is heated until it is completely white in color. The student
Mariulka [41]

Answer:

X = 5

Explanation:

The molar ratio of water to copper(II) sulfate must be found.

The mass of water that must have been eliminated from the salt is found by the difference in weight before and after:

(500 g) - (320 g) = 180 g water eliminated

The moles of water (MW 18.02 g/mol) is then found:

(180 g) / (18.02g/mol) = 9.9889...mol

The mass of the dehydrated copper(II) sulfate (MW 159.609 g/mol) is converted to moles:

(320 g) / (159.609 g/mol) = 2.004899...mol

The molar proportion of water to the copper(II) sulfate is then calculated:

(9.9889...mol H₂O) / (2.0034899...mol CuSO₄) ≅ 5

The nonvolatile, nonelectrolyte testosterone, C19H28O2 (288.40 g/mol), is soluble in benzene C6H6. Calculate the osmotic pressur
dolphi86 [110]

Answer:

3.824 atm

Explanation:

From the ideal gas equation

P = mRT/MW × V

m is mass of testosterone = 12.9 g

R is gas constant = 82.057 cm^3.atm/mol.K

T is temperature of benzene solution = 298 K

MW is molecular weight of testosterone = 288.40 g/mol

V is volume of benzene solution = 286 ml = 286 cm^3

P = 12.9×82.057×298/288.4×286 = 3.824 atm

Feliz [49]
A. and D. would be the best pick for this sort of experiment, but maybe (unlikely) B. because you could see how they could react in certain situations, how they react to danger but I suggest A.

Hope this helps you ☁︎☀︎☁︎
