A 2-column table with 4 rows. The first column titled mineral has entries diamond, cubic zirconia, common glass, ruby. The second column titled density and grams per cubic centimeter has entries 3.50 to 3.55, 5.50 to 5.90, 2.40 to 2.80, 3.90 to 4.10.
If a rock sample has a mass of 1.17 g and a volume of 0.33 cm3, what type of rock is it?
If a rock sample has a mass of 2.7 g and a volume of
1.1 cm3, what type of rock is it?
If a rock sample has a mass of 11.2 g and a volume of 1.9 cm3, what type of rock is it?
To determine the type of rock, we need to compare the density of the rock sample with the densities listed in the second column of the 2-column table.
For the first question:
The density of the rock sample is calculated by dividing the mass by the volume.
Density = Mass / Volume = 1.17 g / 0.33 cm^3 = 3.55 g/cm^3.
Comparing the density of the rock sample (3.55 g/cm^3) with the densities listed in the table, it matches with the entry "diamond" in the first column. Therefore, the type of rock is diamond.
For the second question:
Density = Mass / Volume = 2.7 g / 1.1 cm^3 = 2.45 g/cm^3.
Comparing the density of the rock sample (2.45 g/cm^3) with the densities listed in the table, it matches with the entry "common glass" in the first column. Therefore, the type of rock is common glass.
For the third question:
Density = Mass / Volume = 11.2 g / 1.9 cm^3 = 5.89 g/cm^3.
Comparing the density of the rock sample (5.89 g/cm^3) with the densities listed in the table, it matches with the entry "cubic zirconia" in the first column. Therefore, the type of rock is cubic zirconia.
To determine the type of rock based on its mass and volume, we can compare the density of the rock with the density ranges given in the table.
1. For a rock sample with a mass of 1.17 g and volume of 0.33 cm3:
- Density = mass / volume = 1.17 g / 0.33 cm3 ≈ 3.55 g/cm3
- Comparing the density with the given density ranges in the table:
- The density falls within the range of 3.50 to 3.55 g/cm3.
- Corresponding mineral: Diamond
2. For a rock sample with a mass of 2.7 g and a volume of 1.1 cm3:
- Density = mass / volume = 2.7 g / 1.1 cm3 ≈ 2.45 g/cm3
- Comparing the density with the given density ranges in the table:
- The density falls within the range of 2.40 to 2.80 g/cm3.
- Corresponding mineral: Common glass
3. For a rock sample with a mass of 11.2 g and a volume of 1.9 cm3:
- Density = mass / volume = 11.2 g / 1.9 cm3 ≈ 5.89 g/cm3
- Comparing the density with the given density ranges in the table:
- The density falls within the range of 5.50 to 5.90 g/cm3.
- Corresponding mineral: Cubic zirconia
