What are the main characteristics of matter in terms of its states? 
 
 The main states of matter are solid, liquid, and gas. Solids have a definite shape and volume, 
liquids have a definite volume but take the shape of their container, and gases have neither 
definite shape nor volume, expanding to fill their container. 
 
How do you convert between different units of measurement for volume, such as lite...

actual yield 
the experimental quantity, in grams, of product obtained in a 
reaction. 
Avogadro’s number 
the number of particles (6.022 x 10^23) of a substance in 1 mol of 
that substance. By definition, Avogadro’s number is equal to the 
number of carbon-12 atoms in exactly 12.00 g of carbon-12.
