The concentration of the HCl solution is 0.047 M.
Explanation:
Data given about acid and base:
volume of acid Vacid = 46.9 ml
molarity of acid =?
volume of the base (NaOH) = 16.4 ml
molarity of the base = 0.135 M
To know the concentration of the acid in this reaction, the formula used in titration is used. It is
Macid X Vacid = Mbase X Vbase
the formula is rewritten as:
Macid =
putting the values in the equation:
Macid =
= 0.047 M
the concentration of the acid i.e HCl in the solution is of 0.047 M.
Answer : The correct option is, (d) inversely proportional to volume and directly proportional to the kelvin temperature
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
Combined gas law : It is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
or,
From the above information we conclude that the pressure exerted by a gas is inversely proportional to volume and directly proportional to the kelvin temperature.
Hence, the correct option is, (d)
