How can the solubility of alcohols be estimated?

Alcohols often have trouble dissolving in water because of different polarities of the two liquids (water and an alcohol). The more carbon chains it has, the harder it is for it to dissolve. That's why methanol, ethanol and propanol are miscible while all those above it are not, meaning they don't create a homogeneous mixture.

44.04 g/mol

Explanation:

Ideal gas law in terms of density:

where,

P = pressure of the gas  = 0.789 atm

V = volume of the gas

T = temperature of the gas  =

n = number of moles of the gas

R = gas constant = 0.0821 Latm/moleK

M = molar mass of gas

w = mass of gas

= density =1.43 g/ml

Thus molar mass of the gas is 44.04 g/mol
