3 percent by volume / volume (percent volume / volume,% v / v) is to say the volume of solvent that is present in 100 unit volume solution
of ethanol (C2H6O) 10 cm3 + 90 cm3 water into a slurry. 100 cm3 solution with a concentration of 10 percent by volume / volume or 10% v / v
3.1 If this solution to 50 cm3 is dissolved C2H6O few grams. (Density of C2H6O pure = 0.8 g / cm3)
How do * solution with a concentration 10% v / v solution 100 cm3 with C2H6O dissolved 10 cm3 solution of 50 cm3, with C2H6O 6 dissolved = five o'clock cm3 * density of C2H6O pure. = 0.8 G / cm3 C2H6O 1 cm3 heavy G = 0.8 = 0.8 x 5 C2H6O 5 cm3 heavy G = G 4.0.
