Answer:

1.932 kg

Explanation:

First we convert 100.0 mL to L:

  • 100.0 mL / 1000 = 0.1000 L

Then we calculate the mass of the substance, using the definition of density:

  • Density = mass / volume
  • mass = density * volume
  • 19.32 kg/L * 0.1000 L = 1.932 kg

As the multiplication involves two numbers of 4 significant figures each, the answer needs to have 4 significants figures as well.
