Question

8. A student filled a graduated cylinder with water and read the meniscus at 25.8 mL. The student

then dropped a solid material into the graduated cylinder and the water level rose to 35.9 mL. If
the solid material had a density of 2.99 g/mL, determine the mass of the solid object.

Answer 1

30.2 g

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

volume = final volume of water - initial volume of water

From the question

volume = 35.9 ml - 25.8 ml = 10.1 mL

We have

mass = 2.99 × 10.1 = 30.199 g

We have the final answer as

30.2 g
