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.
Your answer depends on the construction of the cotton fibre and the substance that is the other 20%.
The density of methanol at room temperature (20°C) is about 0.7918 grams per cubic centimeter.
To find the density of methanol, you would need to divide the mass of a given volume of methanol by its volume. The formula for density is density = mass/volume. The density of methanol at room temperature (20°C) is approximately 0.7918 g/cm³.
20% of 20% is 4% (=0.04)
20 percent out of 100 is 20 percent. 100 percent is all you can have. 20 is one fifth. 5x20=100
12 percent of 20 percent is 0.024 or 2.4%
7 of out 20 in percent is (7/20)*100 = 35 percent.
20 percent of 80 percent = 0.16 or 16%
percent of 4/20 = 20%4/20 * 100% = 20%
20% = .20 20% of 1m = .20 * 1m = 0.2m
"percent" means "out of 100"20 percent of 5000 is:20/100 x 5000 = 1000Correct - as far as it goes.But the question was not 20 percent of 5000, it was 20 percent of 5000 percent.So the answer is 1000 percent. And that, in turn, gives the correct answer of 10
20 percent of 42 = 8.4
