If this same volume of liquid had been chloroform (d = 1.48 g/mL), how much would it weigh?

Question

2. A 12.2 mL sample of liquid was found to have a mass of 10.4 g.
a) Calculate the density of this liquid (in g/mL).

Answer 1

For 2a, remember the formula for density: D= mass/volume

 

The density of the unknown liquid would then be D= 10.4 g/ 12.2 mL. Therefore the density of the unknown liquid would be D= 0.852 g/mL

 

For (what I am assuming is) 2b, to find the mass of 12.2 mL of chloroform, you just have to rearrange the formula:

 

Density= mass/ volume (multiply both sides by volume)

Density (g/mL) * volume (mL)= mass (g)

1.48 (g/mL) * 12.2 (mL) = mass (g)

mass= 18.1 g
