A solution is made by mixing equal masses of ethanol C2H6O and methanol CH4O Determine the mole fraction of each component to at least three significant figures?
Adlerlove
First figure the molar mass for each...C2H6O=46 & CH4O=32. Together C2H6O(46)+CH4O(32)= 78
Now you take molar mass / total molar mass
So C2H6O(46)/total mass (C2H6O+CH4O)78= C2H60 or ethanol=0.410
and CH4O(32)/total mass 78=CH4O or methanol=0.589

25%
What is the volume and mass of alcohol?
The answers will depend on whether you mean a drop of alcohol or a bottle or a vat. Furthermore, it will depend on the type of alcohol: methanol, ethanol, propanol, etc.
Which substance would most behave as an ideal gas at stp choose one answer a n2 b h2o c ch3oh d hf?
i think its a and may be c bcz both are non polar and has weak forces of attraction . bt nitrogen has low mass as compared to methanol so may be nitrogen is the right answer.

Why intake of methanol in very small quantities can cause death?
intake of methanol in a small amount can cause death. methanol gets oxidised into methanal reacts with cell component which results in coalugation of cell content
