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.
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?
