Answer: The number of moles of the weak acid in the solution is 0.00396
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a) 
The balanced chemical reaction is:
1 mole of base uses = 1 mole of 
0.00396 moles of base use = 
moles of
Thus the number of moles of the weak acid in the solution is 0.00396
324.05 degrees K
To get from C to K just add 273.15
The balanced chemical equation that illustrates this reaction is:
<span>C2H4 + 3O2 --> 2CO2 + 2H2O
</span>
From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 gram
Therefore:
molar mass of C2H4 = 12(2) + 4(1) = 24 + 4 = 28 grams
number of moles = mass / molar mass
number of moles of C2H4 = 54.7 / 28 = 1.95 moles
From the balanced equation above:
3 moles of oxygen are required to react with one mole of C2H4, therefore, to know the number of moles required to react with 1.95 moles of C2H4, all you have to do is cross multiplication as follows:
number of oxygen moles = (1.95*3) / 1 = 5.85 moles

HCI are less soluble in water as the temperature of the solution is increased.
