Chapter 17, Problem 2PEA

To determine

The specific gravity of the sodium plagioclase feldspar has the mass of $25.09\text{ g}$ where its length, width, and height are measured as $2.89\text{ cm}$ , $1.86\text{ cm}$ , and $1.79\text{ cm}$ respectively. Also, check whether sodium plagioclase feldspar crystallizes at high temperature or low temperature on

Bowen’s reaction series.
