Question

the mass of sample X is 20.0g. it was placed in a graduated cylinder and the water level rose from A to B. what is the density of sample X? pay close attention to significant figures

Answer 1

Answer: 4.0 g/mL

Step-by-step explanation:

The volume increased by 5.0 mL. Recall that the number of significant figures is equal to the number of certain values you can read plus one. Here, the volume increased from 14.0 mL to 19.0 mL, so the volume of X is 5.0 mL.
