Question

A 3.689 g object is added to 7.29 mL of water causing the water level to rise to 8.54 mL. What is the density of the object?

Answer 1

answer: 2.95 g/mL

explanation: first you find the difference between the previous and current water level:

8.54-7.29=1.25

then you place 3.689g over 1.25mL then divide:

you get 2.9512

due to significant #'s the answer is rounded and turned into:

2.95 g/mL

hoped this helped and that it's actually right-_-
