What is the ratio of the concentration of the substance in the flask Flask of the same volume is filled with ammonia gas and hydrogen chloride gas respectively under the same temperature and pressure. After the fountain experiment, water is filled with the flasks. What is the ratio of the concentration of the substance in the flask Flasks of the same volume under the same temperature and pressure were filled with ammonia gas and hydrogen chloride gas respectively. After the fountain experiment, the water was filled with the flasks. What is the ratio of the concentration of the substance in the flask
Analysis: if the flask volume is V (L), then the amount of substance containing ammonia gas and hydrogen chloride gas is n=V/Vm (Note: Vm is the molar volume of gas)
Because ammonia and hydrogen chloride gas are easily soluble in water and water is filled in the flask, the volume of solution is VL.
So C1= C2= n/V = V/Vm/V =1/Vm
Therefore, the concentration ratio of substances in the flask is 1:1.

Both ammonia and hydrogen chloride are known to be used in fountain experiments. If ammonia and chlorine% B are each collected in an equal volume flask at the same temperature and pressure It is known that both ammonia and hydrogen chloride can be used as the gas for fountain experiments. If ammonia and hydrogen chloride are collected in equal volume flasks under the same temperature and pressure, why is the relationship between the two flasks solutions after the experiment the same amount and concentration of substance and the different mass fraction of solute? Both ammonia and hydrogen chloride are known to be used in fountain experiments. If ammonia and chlorine% B are collected in equal volume flasks at the same temperature and pressure It is known that both ammonia and hydrogen chloride can be used as the gas for fountain experiments. If ammonia and hydrogen chloride are collected in equal volume flasks at the same temperature and pressure, why is the relationship between the two flasks solution after the experiment that the concentration of substance is the same and the mass fraction of solute is different?
Three conditions of equal temperature and pressure and equal volume indicate that the amount of matter of the two gases is the same
Upon completion of the experiment, the flask was completely filled with water and the volume of water was the same (both flask volumes)
The amount concentration of the substance is: the amount/volume of the solute substance so that the two gases are the same
However, the correlation between the mass fraction and the relative molecular mass of solutes should be different between the two gases.
