Chapter 2, Problem 3E

Summary Introduction

To calculate: The amounts of molecules present in H₂O are in one spoonful of water that holds about 18mL water.

Concept introduction: The mass of the molecule is denoted as molecular mass. Molecular mass is calculated by the addition of atomic mass of atoms and by division of number of atoms present in a certain element. It is known as atomic mass unit (amu). The number of molecules should be calculated by the density of water, number of moles in the given volume, and molecular mass.
