Expert Solution
Step 1: Introduction

To calculate the volume of calcite and aragonite we need to calculate specific gravity. 

The specific gravity of a mineral is defined as the ratio of weight of the mineral in air and the weight of equal volume of water. 

Let the weight of mineral in air =  Wa

Weight of mineral in water = Ww

Then specific gravity is given by, 

Sp. Gravity = Wa/(Wa-Ww) --------------1 

Another formula for specific gravity is,

Specific gravity = Density of mineral/Density of water 

Density of mineral = sp. Gravity × Density of water 


From equation 1 and equation 2 we can find out the density of two mineral then,

We know density = mass/volume 

Volume= mass/density-----------3
