Answer:
Explanation:
Given , molarity of glycerol=
Volume= 1 L.
Therefore, No of moles of glycerol=
Now, volume of water needed, V=998.8 mL.
Density is given as= 0.9982 g/mL.
Therefore, mass of water =
Now, molality=
Hence, this is the required solution.
Answer:
The molarity of the acid HX is 6.0 M.
Explanation:
We determine the amount of moles of KOH used to neutralize the acid:
=0.12 moles KOH
Then, we calculate the amount of moles of acid:
0.12 moles KOH×=0.12 moles HX
The molarity of HX is:
=6.0 M
<u>Answer:</u> The expression for is written below.
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
The partial pressure for solids and liquids are taken as 1.
For the given chemical equation:
The expression for for the following equation is:
The partial pressure of will be 1 because it is solid.
So, the expression for now becomes:
Hence, the expression for is written above.
