    ETHANOL (C2H5OH) HAS A DENSITY OF 0.80g/ml. IF A 10%(v/v) MIXTURE OF ETHANOL IN WATER WAS PREPARED HOW MANY GRAMS OF ETHANOL WOULD BE IN 100ML OF THE MIXTURE? (ASSUMING MIXED VOLUME IS THE SUM OF THE PARTIAL VOLUME)

    A stock solution of ethanol is made by weighing out the correct amount of absolute ethanol in a tared beaker containing 15 ml of water. Why is it necessary to add water to the beaker before adding the ethanol?
