Question

You need to determine the mass of an aqueous solution. You determine the mass of your 10.0 mL graduated cylinder to be 23.731 g. After adding a volume of 3.12 mL of solution to the cylinder, you reweigh it and determine the new mass to be 26.414 g. What is the density of the liquid?

Answer 1

Answer: 0.86g/mL

Step-by-step explanation:

Mass of empty cylinder = 23.731g

Mass of cylinder + liquid = 26.414g

Mass of the liquid = 26.414 — 23.731

= 2.683g

Volume of the liquid = 3.12mL

Density = Mass / volume

Density = 2.683g / 3.12mL

Density = 0.86g/mL
