Question

what will be the molarity of Ethanol if number of moles of solution is 1 and some amount of Ethanol is dissolved in 126 gram of water​

Answer 1

Answer:

No of moles(water)=126/18=7 mol

 No of moles=volume in liters/22.4

 7=Volume in L/22.4

Volume in L=22.4*7=156.8

Therefore Molarity=no of moles of solute/volume of solution

                                   =1/156.8=0.006377 M (approximate)
