Answer: mole fraction of methanol = 0.590
mole fraction of ethanol = 0.410
Explanation:
We are given:
Equal masses of methanol 
and ethanol 
are mixed.
let the mass be x g.
Calculating the moles of methanol in the solution, by using the equation:
Calculating the moles of ethanol in the solution, by using the equation:
To calculate the mole fraction of methanol, we use the equation:
To calculate the mole fraction of ethanol, we use the equation:
Thus mole fraction of methanol is 0.590 and mole fraction of ethanol 0.410 in three significant figures.
Answer:
Hydroxyl
Explanation:
A hydroxyl group is a functional group that attaches to some molecules containing an oxygen and hydrogen atom, bonded together. Also spelled hydroxy, this functional group provides important functions to both alcohols and carboxylic acids.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, given the 1.00-kg of 12.5% ore, we can compute the theoretical yield of copper (II) oxide via stoichiometry:
Whereas the third factor accounts for the percent purity of the covellite. Then, given the percent yield, we can compute the actual yield by:
