Methanol has a density of 0.79 what would the mass of 589mL of methanol be?

To solve this question you need to use the formula, density = mass/volume. So the equation would be 0.79 = mass/589mL. The answer is 465g.

What is the molecular shape of the oxygen in methanol?
Methanol has a tetrahedral shape. Oxygen by itself would have a bent shape when bonded with hydrogen and carbon
How can remove the ammonia from methanol?
assuming it's trace ammonia in lots of methanol, you can probably just heat the methanol to boiling and that should get rid of all the ammonia. molecular sieves (size 3 angstroms) would also probably work. if it's more than a trace amount, you can go for distillation.
Why would someone test electrical conductivity with a solution containing both methanol and water?
because distilled water does not conduct electricity and tap water does and also to see weather methanol conducts electricity.
How do you separate a mixture of acetone and methanol?
A distillation would probably work pretty well.
Ethanol and methanol can be distingushed by?
They would be very difficult to tell apart. Similar in taste and smell. Similar densities. Methanol boils at 65°C but ethanol boils at 78°C so that might help. Hopefully the label on the bottle would tell you.
Can a block of ashwood float in Methanol?
No, not any substance, but some, and here's why. Methanol has a density of 0.79g. If you put something in the methanol, say wood (oak), that weighs 0.89g, which is more, it will sink. It all depends on if it weighs more or less than the methanol. If it weighs more, it will sink, If it weighs less, it will float.
Would methanol be a better or poorer solvent for extraction of cholesterol from egg yolk compared to 2-propanol?
The solubility of cholesterol in methanol is 0.014. 2-propanol would be a better solvent than methanol for the extraction of cholesterol from egg yolk.
What is the molecular shape of the oxygen in methanol?
Methanol has a tetrahedral shape. Oxygen by itself would have a bent shape when bonded with hydrogen and carbon
Can you cool methanol until it becomes a gas?
No. You would have to heat methanol until it became a gas. Same thing with water, and so forth.
What molecules would be expected to form hydrogen bonds in the liquid or solid state ethylene glycol methanol and formaldehyde?
ethylene glycol and methanol
Methanol CH3OH would act like NaCl or like glucose?
Methanol, glucose and sodium chloride are very different compounds and they react different.
Why methanol is use in paints?
Actually, it's rarely used in paint, and if it is, it would be as a dryer. Methanol is, however, a basic ingredient used to cut shellac to proper weight for application. Shellac is not paint, though.
How to get ethanol form methanol?
This would never actually be done since both are readily available, but you could oxidise methanol to formaldehyde, treat with MeLi or MeMgBr and workup with acid.
Is 20 percent methanol a hazardous material?
Methanol is considered hazardous because it can cause irritation and blindness. If you drink to much methanol you can go blind. I am not sure how much quanitiy wise it is. I deal with 100% methanol and get it on my skin. It evaporates extremely fast and makes my hands feel cold. Even with gloves on the cold effect still happens. Read your MSDS in your labaratory for more information on Methanol and the concentration of methanol that you possess. In case you didn't know methanol's formula is 1 carbon and 4 hydrogen and 1 oxygen. If you add a carbon and a few hydrogens you get ethanol. Ethanol's formula is 2 carbons and 6 hydrogens and 1 oxygen. Ethanol is the alcohol is your drinking alcohol. Back in the 19th century and before this time people would try to distill ethanol but they mistakenly made methanol. They would drink drink the methanol in error and become blind because of this. This process of making homemade alcohol (moonshine) of course is illegal and still is.
How can you safely transport methanol?
There are a few safety precautions that I would advise for transporting methanol. Since it is toxic, transport it in sealed containers so that you don't inhale the vapor. And since it is flammable, don't smoke or have other open flames in your vehicle, just in case (even though, if the methanol stays in the sealed containers it shouldn't catch fire anyway). Other than that, you would transport methanol in much the same way that you would transport any other liquid.
Would Solutions of water and methanol makes hazy liquid?
Water and methanol are completely miscible (they will dissolve into each other in any proportion). A mixture of water and methanol will always form a clear solution (after sufficient mixing) unless there are impurities in either to start off with.
How can remove the ammonia from methanol?
assuming it's trace ammonia in lots of methanol, you can probably just heat the methanol to boiling and that should get rid of all the ammonia. molecular sieves (size 3 angstroms) would also probably work. if it's more than a trace amount, you can go for distillation.
