How do you convert moles to atm?
Calculate the pressure of the gas, P, in units of atmospheres according to P = nRT / V. For example, if the sample of gas occupying 623 liters at 299 Kelvin represents 55 moles of gas, then P = (55 x 0.08206 x 299)/623 = 2.17 atmospheres.

What makes a pascal?
A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. … This unit is inconveniently small for many purposes, and the kilopascal (kPa) of 1,000 newtons per square metre is more commonly used.
How do you convert pascal to joules?
Because the kilopascal is a unit of pressure, you cannot convert it directly to joules, which is a unit of energy. Think of joules as the product of a volume measurement and kilopascals, however, and you can easily make the conversion. A pascal equals 1 kg per meter seconds squared.
Why is atm 760 mmHg?

Why is CH3OH toxic?
Methanol has a high toxicity in humans. As little as 10 mL of pure methanol when drunk is metabolized into formic acid, which can cause permanent blindness by destruction of the optic nerve.
Can you drink methanol?
Drinking just 25-90 mL (0.7-3.0 ounces) of methanol can be fatal without proper medical treatment. Since methanol is an industrial chemical, it should not be consumed in any quantity, just as people would normally not mix gasoline or other industrial chemicals into legitimate alcoholic beverages.
