Amineral sample has a mass of 75g. when the sample is dropped into a graduated cylinder with the volume of 20 ml, the volume of the graduated cylinder rises up 40 ml. what is the density of this shape? 3g/ml 1.7g/ml 3.75g/ml 1.15g/ml

i'd say that the moon rock is about 2.2 billion years old.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
