A group of geology students found an unidentified rock weighing 15.5 grams during their field trip. To identify the rock, they decided to calculate its density. They measured the volume of the rock by submerging it in a cylinder filled with water. They then compared the calculated density with the density ranges provided in their geology textbook.
Coal
Dolomite
Peridotite
Sandstone
While on a mountain climbing expedition, John found an intriguing stone. He noticed that the stone could scratch his glass water bottle,
but not his steel pocket knife.
Based on the Mohs Hardness Scale, what can John infer about the stone?
It is harder than quartz, but softer than topaz.
It is harder than corundum, but softer than gypsum.
It is harder than calcite, but softer than fluorite.

A geologist found an irregularly shaped rock during his field trip. He decided to measure its density. He lowered the rock into a graduated cylinder which initially had a volume of water equal to 50 ml. After placing the rock, the water level rose to 75 ml. The rock's mass was found to be 250 g. What was the density of the rock?
15 g/mL
5 g/mL
10 g/mL
20 g/mL
