1 calculate the numbers of moles of 2-butanol


1. Calculate the numbers of moles of 2-butanol that needed to dissolved in ethenol(125gms) just to form 12 m 2 butanol soln also find out  mass of 2-butanol ?

2. Using a  solution of ethanol  in water is formed by dissolving 80.6 mL of ethanol  that has density = 0.79 g/cm3 and amount of water to produce a solution of 250 mL, now find out the  molarity of the ethanol (C2H5OH) in this solution?
