20.016 grams – 18.246 grams = 1.770 grams (mass of unknown substance)
1.0 g/ml + 0.79 g/ml + 0.92 g/ml = 2.71 g/ml (density of unknown substance)
1.77 grams / (x) ml = 2.71 g/ml
1.77 / x = 2.71
2.71x / 2.71 = 1.77/2.71
x = 0.653 ml = (Volume of the unknown substance)
20.016 – 18.246 = 1.77 grams
now we calculate its volume:
1) water:1.77 / 1.0 = 1.77 ml
2) ethanol: 1.77 / 0.79 = 2.24 ml
3) coconut oil: 1.77 / 0.92 = 1.9 ml
the only thing that we need is the volume of the unknown liquid substance or glass cylinder.
