Question

20. Gabriel is determined to find the density of an unknown, irregularly shaped object. Using a digital scale to get the mass and the displacement method to get the volume, he records the following data: (6 points) Mass-19.37 g Initial volume-50.00 mL Final volume- 61.94 mL What is the density of the unknown object? PLEASE SHOW YOUR WORK!​

Answer 1

Density of irregular object = 1.62 g/mL

Step-by-step explanation:

Density of a substance = mass of substance /volume of substance

Mass of substance as measured from the scale = 19.37 g

Volume of the object spins determined bynthe displacement method since itnis an irregular object. In this method, the object whose volume is required is immersed in a measuring cylinder containing a known volume of water. The new volume of water after the immersion of the object is recorded. The volume of the irregular object is then obtained by finding the difference between the final and initial volume of water. This is so because a solid immersed in a liquid will displace its own volume of the liquid.

Volume of irregular object = 61.94 mL - 50.0 mL = 11.94 mL

Density of irregular object = 19.37 g / 11.94 mL

Density of irregular object = 1.62 g/mL
