In order to calculate the volume of 0.0023 moles of CO2, we use the ideal gas law and understand that one mole of an ideal gas at standard temperature and pressure occupies a volume of 22.4 liters. The volume for 0.0023 moles of CO2 is found to be approximately 0.05152 liters.
To solve for the volume of the 0.0023 moles of CO2, we need to use the ideal gas law, PV=nRT, where P depicts the pressure, V signifies the volume we need to find, n equals the number of moles, R denotes the universal gas constant, and T denotes the temperature. Assuming the relationship takes place at standard temperature and pressure (STP, 0 degrees Celsius, 1 atm), we can solve for V.
At STP, 1 mole of any ideal gas occupies a volume of 22.4 liters. Therefore, V = n * (Volume of 1 mole at STP), which equals 0.0023 moles * 22.4 L/mole = 0.05152 liters.

Answer: The energy of the wave increases by a factor of 9
Explanation:
3 x 3 = 9
It is a strong base and a very poor conductor of electric current.
B.
It is a strong acid and a very good conductor of electric current.
C.
It is a weak base and a very good conductor of electric current.
D.
It is a weak acid and a poor conductor of electric current.
Substance A is mixed with water and donates 0.4% of its H⁺ ions, therefore given substance is a weak acid & show poor conduction of electric current.
According to the Arrhenius theory of acids and bases, acids are those species which gives H⁺ ion to the solution.
In the question it is given that, substance A is mixed with water and it donates H⁺ ion, from this it is clear that given substance is acid. It is also mention that it donates only 0.4% of its H⁺ ion means partial dissociation is observed, so we conclude that this acid is weak in nature. And due to weak dissociation and less number of available H⁺ ion it did not conduct electricity effectively.
Hence, option (D) is correct i.e. it is weak acid and a poor conductor of electric current.
