Question

Mole fraction of ethanol in a solution containing 46g of ethanol and 90g of water is

Answer 1

Answer:

1/6=0.166

Explanation:

mole fraction of ethanol(C2H5OH)=number of moles of ethanol/number of moles of ethanol+number of moles of water

number of moles of ethanol=46/46=1

number of moles of water=90/18=5

mole fraction of ethanol=1/1+5=1/6=0.1666
