What is the density of isopropyl alcohol?
How much does 1 mL of isopropyl alcohol weigh?
1 milliliter of isopropyl alcohol weighs 0.785 gram. 0.7854 gram precisely.
Will 70 percent rubbing alcohol freeze?
According to the Department of Physics at the University of Illinois Urbana-Champaign, a solution with 30 percent ethanol concentration, or 60 proof, has freezing point of 5 degrees F or -15 degrees C, and one with 40 percent ethanol concentration, or 80 proof, freezes at -10 degrees F or -23 degrees C — therefore, 70 …
What is the flashpoint of 70 alcohol?
Flash Point: 17°C (63°F) CC. LEL 3.3%. Autoignition Temp.: 363°C (685°F).
What is the difference between isopropyl alcohol and rubbing alcohol?
The difference between rubbing alcohol and more pure forms of isopropyl alcohol is that rubbing alcohol contains denaturants which make the solution unpalatable for human consumption.
What’s the difference between isopropyl alcohol and hydrogen peroxide?
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
Is isopropyl alcohol more dense than water?
The liquids must have different densities because the ice cube floats in one but sinks in the other. … Since ice sinks in isopropyl alcohol, alcohol must be less dense than ice. This means that water and isopropyl alcohol must have different densities and that the water is more dense than isopropyl alcohol.
Is isopropyl alcohol safe for skin?
Isopropyl alcohol is readily absorbed through the skin, so spilling large amounts of IPA on the skin may cause accidental poisoning. Small amounts of IPA on the skin is generally not dangerous, but repeated skin exposure can cause itching, redness, rash, drying, and cracking.
Is isopropyl alcohol good for cleaning electronics?
Household rubbing (isopropyl) alcohol is great for cleaning electronics. It kills fungus, bacteria and viruses, including E. … Isopropyl or rubbing alcohol is what you want for cleaning electronics.
Does isopropyl alcohol fully evaporate?
Pure isopropyl alcohol would normally evaporate completely at room temperature in our standard atmosphere. If there is a residue, it is due to dissolved or suspended impurities, including anything it may have dissolved from the surface that it is evaporating on.
How much does 5 gallons of isopropyl alcohol weigh?
US gallon to Kilogram Conversion Chart – Isopropyl alcohol
|US gallons to kilograms of Isopropyl alcohol|
|5 US gallons||=||14.9 kilograms|
|8 US gallons||=||23.8 kilograms|

How do you convert mL to alcohol in grams?
Multiply the volume in milliliters by the density.
For example, to convert 10 mL of ethanol to grams, look up the density of ethanol: 0.789 g/mL. Multiply 10 mL by 0.789 g/ml, and get 7.89 grams. Now you know that 10 milliliters of ethanol weighs 7.89 grams.
How much does 1 gallon water weigh?
One US liquid gallon of fresh water weighs roughly 8.34 pounds (lb) or 3.785 kilograms (kg) at room temperature.
