Question

Student 1You are supplied with a 100 mL beaker that you weigh on a pocket balance – its weight clean and dry is 29.3 g. You then dispense 15.0 mL of a clear unknown liquid from a graduated cylinder into the 100 mL beaker. The beaker plus liquid now weighs 44.2 g. Calculate the density of the liquid on the sheet supplied with your data sheets.

Answer 1

Answer:

The answer to your question is: density = 0.993 g/ml

Explanation:

Data

mass beaker empty = 29.3 g

volume of liquid = 15 ml

mass beaker + liquid = 44.2 g

Formula

             density = mass / volume

Process

mass of liquid = 44.2 - 29.3

                       = 14.9 g

             density = 14.9 / 15

                          = 0.993 g/ml
