What is the molar mass of the volatile liquid?
If the substance in question is a volatile liquid, a common method to determine its molar mass is to use the ideal gas law, PV = nRT. Because the liquid is volatile, it can easily be converted to a gas. While the substance is in the gas phase, you can measure its volume, pressure, and temperature.
How does molar mass affect volatility?
Molecular weight In general, volatility tends to decrease with increasing molecular mass because larger molecules can participate in more intermolecular bonding, although other factors such as structure and polarity play a significant role.
How do you find the molecular weight of a volatile liquid?
Knowing the mass and the number of moles will allow us to compute the molar mass of the liquid: molar mass = (mass)/(number of moles).
How do you identify a volatile liquid?
Scientists commonly use the boiling point of a liquid as the measure of volatility.
- Volatile liquids have low boiling points.
- A liquid with a low boiling point will begin to boil faster than liquids with higher boiling points.
What is volatile liquid?
A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The term volatile usually applies to liquids.
How will the determination of the molar mass of a volatile liquid be affected if the Florence flask is heated too rapidly?
The molar mass of the vapor will be considered too high because the mass of the oil will be factored in as weight from the vapor.
Which is a more volatile liquid?
Presence of hydrogen bonding in a liquid decreases its volatile nature. This is because due to hydrogen bonding, there is more association between the molecules and the tendency to go into gaseous phase decreases. Hence, C6H6 will be more volatile liquid since it has no hydrogen bonding. Was this answer helpful?
What is a volatile material explain?
Volatile matter is an unstable material. Volatile matter tends to not remain in one state and will rapidly transition to another state, or vaporize, when the right conditions are met. Volatile matter has its volatility determined not by temperature but more so by the vapor pressure required to initiate a phase change.
How would the molecular weight for a volatile liquid be affected if the balance you did your weighing on had an error of 2.3 g choose the best answer?
1. If the weight has an error of 2.3 g, the resulting mass of volatile liquid will be less than its actual mass.
How is the mass of the vaporized liquid determined in this experiment?
How is the mass of the vaporized liquid determined in this experiment? The mass of the vaporized liquid is the mass of the vapor and flask minus the mass of the flask.
What makes a liquid volatile?
A substance is said to be volatile if it boils at a low temperature, changing from the liquid to the gas phase.
Which of the following is a volatile liquid?
Bromine is a volatile liquid. Was this answer helpful?
