Molarity = Nª moles CaCl2 in 1 liter of ethanol.
Volume of ethanol = Mass of ethanol / ethanol´s density

Molar mass of Ca(OH)2 = 74
Molar mass of C2H5OH = 46 g
Molarity = (27/74)/(480/46) = 0.0349662162 M

if you get the book catchup chemistry it explains how to work out molarity on page 51/52/53
concentration=number of moles / volume in litres=n/v= concentration in mol l-1
