Calculate the mass of propylene glycol that must be added to 0.340 kg of water to reduce the vapor pressure by 2.88 ATM at 40 degrees Celsius at 40 degrees Celsius equals 55.3torr?
To calculate the mass of propylene glycol needed, we can use Raoult's law. Given that the vapor pressure of pure water at 40 degrees Celsius is 55.3 torr and the desired vapor pressure when mixed is 2.88 atm, we can calculate the mole fraction of propylene glycol needed. From this, we can find the mass of propylene glycol required to achieve this mole fraction when combined with 0.34 kg of water.
Where does the vapor in electronic cigarettes come from?
The vapor comes from the flavored liquid inside the e-cig. The liquid (usually made of a mix of propylene glycol and vegetable glycerin, with or without nicotine added) is heated just enough to vaporize it (convert it from liquid to gas).
Is the white smoke from burned automotive coolant toxic?
Yes, very toxic. Antifreeze products usually contain one of three active ingredients: Ethylene glycol Propylene glycol Methanol All three ingredients are toxic to humans in liquid or vapor form.
Is propylene glycol bad for humans?
Propylene glycol is considered safe for humans in small amounts. It is commonly used in food, cosmetics, and pharmaceuticals. However, exposure to large quantities of propylene glycol may cause irritation to the skin, eyes, or respiratory tract.
Is vegetable glycerin vapor safe to inhale?
i like boobies
What will happen when smoke is mixed with vapor?
It's less harsh to inhale.
Natural gas dehydration using triethylene glycol?
Yes dehydration of neutral gas is using triethlene glycol (TEG) because TEG is the best water vapor absorbent.
When you inhale air do you get a small or big amount of water vapour?
Well this depends on the humidity. Lets say the humidity is 20%. This means 20% of the air is water vapor. So approximately 20% of the air you inhale will be water vapor.
Is distilled water vapor safe to breathe?
Distilled water vapor is safe to breathe. It wouldn't be advised to inhale it, however, just like regular steam.
Is triethylene glycol toxic to breath?
Breathing in high concentrations of triethylene glycol vapor can irritate the respiratory tract and cause symptoms like coughing and shortness of breath. Prolonged or repeated exposure to high levels of triethylene glycol vapor may cause more serious health effects. It is important to always use this chemical in a well-ventilated area and follow all safety recommendations.
What are true the vapor pressure of 1 m ethylene glycol C2H6O2 is the same as the vapor pressure of 1 m kCI where the solvent is water is it true or false?
False. The vapor pressure of a solution is lower than that of the pure solvent in a colligative property called Raoult's law. The vapor pressure of a solution is directly proportional to the mole fraction of the solute present, so the presence of the solute (ethylene glycol or KCl) will lower the vapor pressure compared to pure water.
Is electronic cigarettes good for you?
An electronic cigarette is a battery-powered vaporizer which simulates tobacco smoking by producing an aerosol commonly, although incorrectly, called "vapor" that resembles smoke. It generally uses a heating element known as an atomizer, that vaporizes a liquid solution known as e-liquid. E-liquids usually contain a mixture of propylene glycol, vegetable glycerin, nicotine, and flavorings, while others release a flavored vapor without nicotine. So I think it's more safe than the regular cigarette.
