Answer:
Explanation:
The formula of nickeI(II)nitrate hexahydrate is
Ni(NO3)2.6H2O
So option (c) is correct.
Answer:
Piso = 32.17 Torr
Pprop = 5.079 Torr
yprop = 0.1364
yiso = 0.8636
Explanation:
From the question; we can opine that :
- The mole fraction of isopropanol in a mixture of isopropanol and propanol will be 1.
-
The partial pressure of isopropanol will be its mole fraction multiplied by vapor pressure of isopropanol
-
The partial pressure of propanol will be its mole fraction multiplied by vapor pressure of propanol
-
In the vapor, the mole fraction of propanol will be its partial pressure divided by the sum of the two partial pressures
NOW;
When xprop = 0.243; xisopropanol will be 1- 0.243 = 0.757
P°iso = 45.2 Torr at 25 °C so
Piso will be 45.2 × 0.757 = 32.17 Torr
Pprop will be 20.9 × 0.243 = 5.079 Torr
yprop = 5.079/(5.079 +32.17) = 0.1364
yiso = 1-0.1364 = 0.8636
Answer: The molarity of silver nitrate in the diluted solution is 0.015 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the dilution law,
where,
= molarity of concentrated solution = 0.150 M
= volume of concentrated solution = 10.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 100.0 ml
Thus the molarity of silver nitrate in the diluted solution is 0.015 M
