Final answer:
The students most likely measured the mass of the quartz sample using a scale and its volume using the water displacement method.
Step-by-step explanation:
To measure the mass of a quartz sample, the students probably used a balance or scale. This tool allows for precise measurement of mass in grams or kilograms. For the volume, there are several methods that could have been used. If the quartz sample was irregular in shape, they most likely used the water displacement method: they placed the quartz in a container full of water and measured the rise in water level, which corresponds to the volume of the quartz.
