Question

Density is a physical property that relates the mass of a substance to its volume.

Calculate the density, in g/mL, of a liquid that has a mass of 0.125 g and a volume of 0.000225 L.

density:
Calculate the volume in milliliters of a 4.91-g sample of a solid with a density of 3.41 g/mL.

volume:
Calculate the mass of a 0.267-mL sample of a liquid with a density of 0.660 g/mL.

mass:

Answer 1

0.177 g

Step-by-step explanation:

To calculate the density of a liquid, the formula is: density = mass / volume

In this case, the mass is 0.125 g and the volume is 0.000225 L. So the density would be:

density = 0.125 g / 0.000225 L = 555.55 g/mL

To calculate the volume in milliliters of a solid with a known density, the formula is: volume = mass / density

In this case, the mass is 4.91 g and the density is 3.41 g/mL. To convert liters to milliliters, you must multiply by 1000.

volume = 4.91 g / 3.41 g/mL * 1000 mL/L = 1444.85 ml

To calculate the mass of a liquid with a known density, the formula is: mass = density x volume

In this case, the density is 0.660 g/mL and the volume is 0.267 mL.

mass = 0.660 g/mL x 0.267 mL = 0.177 g
