Question

A student filled a graduated cylinder with water and read the miniscus 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. Show all your work.

Answer 1

30.2g

Step-by-step explanation:

Intial volume of water= 25.8ml

Final volume of water= 35.9ml

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

Volume = final volume of water - initial volume of water

Volume = 35.9 ml - 25.8 ml = 10.1 ml

Mass = Density × volume

(m= ρ⋅V)

Mass = 2.99 g/ml × 10.1ml = 30.199 g

Answer= 30.199g= 30.2g
