How Do You Calculate The Specific Gravity Of A Mineral?
Specific gravity is the density of an object relative to the density of water. Specific gravity is considered one of the most important properties of a mineral because it is a constant and quantifiable property, which can be used for comparison. Specific gravity can be invaluable when identifying a mineral. Step 1 Use the measuring tape to measure a piece of string 50 cm long, and cut it to that length with the scissors. Step 2 Tape the string to the balance plate of a zeroed balance beam, allowing it to hang off the table freely. Step 3 Measure the mass of the mineral sample in air by placing it on the balance plate and recording its weight. Step 4 Measure the mass of the mineral sample in water by tying it to the end of the piece of string and letting it hang freely off the table into a beaker of water. Record the weight shown on the scale. Step 5 Calculate specific gravity. Make the calculation by subtracting the mass of the mineral in water from the mass of the mineral in air (the
