What is the density of a mineral sample?
The density of a mineral sample is a measure of its mass per unit volume. It can be calculated by dividing the mass of the sample by its volume. The density of a mineral sample is a characteristic property that can help in identifying the mineral.
What is the density of a mineral sample with a mass of 20g and a volume of 12cm3?
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
What property is the mass of a mineral sample per unit volume?
Its density.
What mineral has the mass of 54 grams?
The mineral with a mass of 54 grams could be quartz, feldspar, or calcite. Minerals have varying densities, so a 54-gram sample of one mineral may occupy a different volume than a 54-gram sample of another mineral.
Is it true that the larger the sample of a mineral the greater its density?
No, the density of a mineral remains constant regardless of the size of the sample. Density is an intrinsic property of the mineral and is determined by its composition and structure. It is typically expressed in units of mass/volume, so a larger sample will have a proportionally greater mass and volume, resulting in the same density.
A student estimated the mass of a sample of powdered sulfur to be 35 g The actual mass of the sample was 42.5 g What was the error in this measurement?
The error in the measurement was 7.5 g. This was calculated by subtracting the estimated mass (35 g) from the actual mass (42.5 g).
How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
Is the density of a mineral considered its mass divided by its volume?
Yes, the standard definition of density is mass divided by volume. This presumes the mineral is uniform throughout the sample.
What equation would you use to express the density of a mineral sample?
density = mass / volume
What measurement must you make to find the density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.

What is the best metric measurement of the mass of a letter?
The best metric measurement of the mass of a letter would be in grams. This unit of measurement is commonly used to weigh small objects like letters due to its precision and convenience.
