1.
Nalubula is investigating changes in mass of substances when certain changes occur
them.
She places some zinc metal in a beaker and finds the mass of zinc
She then again places the sulphuric acid in another container and measures the mass of the acid
She also mixed the zinc metal with sulphuric acid in another beaker and waters until all the zinc
metal was completely dissolved
She then after, finds the mass of the contents of the beaker having the mixture
Sulphuric acid
zinc
