Molecular substances
what are the most important inorganic molecular substances for living beings?
Determination of correct mol. Mass from Roult's law is applicable to :
Carbon compounds containing more than one halogen atom are called polyhalogen compounds. Most of these compounds are valuable in industry and agriculture. Some important polyhalogen compounds are described as follows: Q : Some basic concepts of chemistry an an atom of an element is 10.1 times heavier than the mass of a carbon atom.What is its mass in amu?
