An unknown substance has a mass of 56.8 g and a volume of 23.4 mL. To 3 significant figures, what is the density of this unknown substance in units of g/mL? Note: Give your answer in units of g/mL, but do not explicitly include units in your answer. Only include a number in the box below. If you include a number and a "g/mL" to represent the unit, your answer would be counted wrong.

The density of a substance is calculated by dividing its mass by its volume.

Density = Mass/Volume

Given that the mass of the unknown substance is 56.8 g and its volume is 23.4 mL, we can calculate the density:

Density = 56.8 g/23.4 mL

Calculating this, we get:

Density ≈ 2.428 g/mL

To 3 significant figures, the density of the unknown substance is 2.43 g/mL.
