Question

A CHM 111 student completing Part B recorded the mass of several pieces of dry metal as
23.7412 g.He obtained a graduated cylinder and recorded an initial water volume of 25.0 mL
upon addition of the metal pieces, the water level rose to 27.1 mL
Calculate the density of the metal in units of grams per milliliter. Report only the numerical portion of your answer (and watch your significant figures!).

Answer 1

The density of the metal in units of grams per milliliter is 11.31 g/mL

What is density?

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

How to determine the density of the metal

The following data were obtained from the question:

• Mass of metal = 23.7412 g
• Volume of water = 25 mL
• Volume of water + metal = 27.1 mL
• Volume of metal = 27.1 – 25 = 2.1 mL
• Density of metal =?

Density = mass / volume

Density of metal = 23.7412 / 2.1

Density of metal = 11.31 g/mL
