Kazeer [188]

Answer:

Substance S is GLYCEROL.

Explanation:

Mass of S = 92.09 g

Volume of S = 73.09 mL

Density of S =..?

Density = mass /volume

Density of S = 92.09/73.09

Density of S = 1.26 g/mL

Finally, we shall determine what substance S represent as follow:

Comparing the density of substance S (i.e 1.26 g/mL) with those given in question above, substance S is GLYCEROL.
