IQ2: How are measurements made in chemistry?
Students:
● conduct an investigation to determine that chemicals react in simple whole number ratios by moles
● explore the concept of the mole and relate this to Avogadro’s constant to describe, calculate and manipulate masses, chemical amounts and numbers of particles in: (ACSCH007, ACSCH039)
– moles of elements and compounds 𝑛=𝑚𝑀𝑀 (n = chemical amount in moles, m = mass in grams, MM = molar mass in gmol-1)
This is the prac for demonstrating how chemicals react according to molar ratios.
