(a)

Interpretation Introduction

Interpretation:

The number of moles of water lost during given thermogravimetric analysis has to be calculated.

Concept introduction:

Thermogravimetric analysis:

Thermogravimetric analysis is a kind of thermal analysis in that temperature varies over time to determine mass of sample used for thermogravimetric analysis.  This analysis provides various informations such as phase transition, desorption, absorption, chemisorption, decomposition due to thermal, oxidation and reduction.  It is done on thermogravimetric analyzer.  Thermogravimetric analysis is also known as thermal gravimetric analysis(TGA).

(b)

Interpretation Introduction

Interpretation:

The formula of substance when the mass lost is 19.2% has to be calculated.
