Standard temperature and pressure are 0°C and 1 atmosphere, and of course their equivalents in other units. 0°C=273K, 1 Atm = 101.3 KPa.

From the choices given, the correct answer is (3).

Mg(OH)2 is a sparingly soluble salt with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutr
Solnce55 [7]

Answer:

The ration of the molar solubility is 165068.49.

Explanation:

The solubility reaction of the magnesium hydroxide in the pure water is as follows.

Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)

              [Mg^{2+}][OH^{-}]

Initial      0          0

Equili     +S       +2S

Final      S          2S

K_{sp}=[Mg^{2+}][OH^{-}]

5.61\times 10^{-11}=(S)(2S)^{2}

S=(\frac{5.61\times 10^{-11}}{4})^{1/3}=2.41\times 10^{-4}M

Solubility of Mg(OH)_{2} in 0.180 M NaOH is a follows.

Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)

              [Mg^{2+}][OH^{-}]

Initial      0          0

Equili     +S       +2S

Final      S          2S+0.180M

K_{sp}=[Mg^{2+}][OH^{-}]

5.61\times 10^{-11}=(S)(2S+0.180)^{2}

S=1.46\times 10^{-9}M

Ratio\,of\,solubility=\frac{2.41\times 10^{-4}}{1.46\times 10^{-9}}=165068.49

Therefore, The ration of the molar solubility is 165068.49.

Which statement describes how a basic coffee cup calorimeter works? A) It measures the mass of a substance given the specific he
fomenos
A calorimeter experiment is a set-up that provides insulation so that no heat escapes to the surroundings and all energy can be accounted for. It can be done at either constant volume or constant pressure. So, the answer to this is knowing the mass of water, the specific heat which is an empirical data, and the change in temperature which can be measured using a thermometer. This experiment could measure the mass of an unknown substance added or the specific heat of the substance or the calorimeter. <em>The answer is D.</em>
