Question

Q. In 800 ml solution 46 ml of ethanol is dissolved. Calculate the concentration of Solution?​

Answer 1

Answer:

M= number of moles of solute/volume of solution in litres

molar mass of ethanol=12×2+1×6+16×1=46

moles of ethanol=46/46=1

M = moles of ethanol / volume of solution in litres

M = 1 / 0.8 = 0.125M
