To find the mass of the solution, we can use the formula:

Mass=Volume×DensityMass=Volume×Density

Given:

  • Density of the solution = 3.12 g/mL
  • Volume of the solution = 1.5 mL

Mass=1.5 mL×3.12 g/mLMass=1.5mL×3.12g/mL

Mass=4.68 gMass=4.68g

To express the mass in proper significant figures, we consider that the volume measurement (1.5 mL) has two significant figures. Therefore, the result should also have two significant figures.

So, the correct answer is:

(c) 4.680 g
