    Name Date Lab: Denisty – Solids and Liquids Part 1: Density Background Information: The density of an object is how much “stuff”‚ or molecules‚ a substance is made of. Density is how tightly packed the molecules are. To calculate the density of a substance we need to know the mass (weight) of the substance and the volume (how much space) of the substance. Mass is determined by weighing an object. Volume of regular shaped objects is calculated by measuring

    Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules

    Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of
