Answer : The concentration in mol/L is
Explanation : Given,
Moles =
Volume of solution = 500 mL
Formula used :
Now put all the given values in this formula, we get:
Therefore, the concentration in mol/L is
Using Reference Table H, the vapor pressure of propanone at 45°C is 33 kPa.
The vapor pressure of a substance changes with temperature and can be accurately determined using a Reference Table H in Chemistry. From the table, we see that the vapor pressure of propanone at 45°C is 33 kPa, which corresponds to option (2). This value shows that the vapor pressure of propanone increases as the temperature rises, which is a characteristic feature of volatile substances like propanone.
