Question

A liquid solvent is added to a flask containing an insoluble solid. The total volume of the solid and liquid together is 86.0 mL.. The liquid solvent has a mass of 29.0 g and a density of 0.865g / m L Determine the mass of the solid given its density is 3.25g / mL

Answer 1

The mass of the solid is approximately 11.61 grams.

Explanation:

To determine the mass of the solid, you can first calculate the total mass of the system (solid + liquid) and then subtract the mass of the liquid solvent.

1. Calculate the mass of the liquid solvent using its density and volume:

Mass of liquid = Density × Volume

Mass of liquid = 0.865 g/mL × 86.0 mL = 74.39 g

2. Now, subtract the mass of the liquid from the total mass of the system to find the mass of the solid:

Mass of solid = Total mass - Mass of liquid

Mass of solid = 86.0 g - 74.39 g = 11.61 g

So, the mass of the solid is approximately 11.61 grams.
