Mass/corresponding weight of liquefied phenol = 1.5408 grams
Mass/corresponding weight of propylene glycol = 63.6 grams
Given that :
Total volume of the water bottles = 24 * 15 ml
= 360 ml
Volume of recipe after pure water is added = 100 ml
the number of units required = Total volume of water / volume of recipe
= 360 / 100 = 3.6 units
i) Determine the Mass ( weight ) of liquefied phenol
amount of liquefied phenol = 0.4 ml * 3.6 = 1.44 ml
given that density of liquefied phenol = 1.07 g/ml
∴ mass of liquefied phenol = density * volume
= 1.07 * 1.44 = 1.5408 grams
ii) Mass( weight ) of propylene glycol
amount = 17 * 3.6 = 61.2 ml
density of propylene glycol = 1.04 g/ml
∴ mass of propylene glycol = 61.2 * 1.04 = 63.648 grams
