You can measure how much of something you have by counting individual objects. For example, you can count the number of cookies in a bag or the number of pages in your notebook. There is a name for a number of atoms, ions, or molecules. One mole of a substance is equal to 6.02 x 10^23 atoms, ions, or molecules of that substance. You can determine the number of moles in a substance by obtaining the mass of the substance.

Objectives

• To measure the masses of common compounds and objects

• To calculate the moles and atoms from the experimental masses

a. Salt (NaCl)

b. Sugar (C6H22O11)

c. Chalk (CaCO3)

d. Sand (SiO2)

e. Water (H2O)

f. Balance

g. Spoon

Jean Beltran · Answer 1

Explanation: first use a balance to get the masses of these items. Once the masses of these items are measured, we can then calculate the moles.

The mole is = mass/molarmass
