One mole of all gaseous substances at K and 1 atm pressure occupies a volume equal to CH is the empirical formula of benzene. The molecular formula shows the exact number of different types of atoms present in a molecule of a compound.
C6H6 is the molecular formula of benzene. The substances that react among themselves to bring about the chemical changes are known as reactants, whereas the substances that are produced as a result of the chemical change, are known as products Limiting Reagent- The reactant which gets consumed first or limits the amount of product formed is known as limiting reagent Reactions in Solutions-- The concentration of a solution can be expressed in any of the following ways. Mass Percent is the mass of the solute in grams per grams of the solution.
Volume percent is the number of units of volume of the solute per units of the volume of solution.
Molarity of the solution is defined as the number of moles of solute dissolved per litre dm3 of the solution. It isdenoted by the symbol M. Measurements in Molarity can change with the change in temperature because solutionsexpand or contract accordingly.
Molality- Molality is defined as the number of moles of solute dissolved per g 1 kg of solvent. Molality is expressed as 'm'. Mole Fraction is the ratio of number of moles of one component to the total number of moles solute and solvents present in the solution.
It is expressed as 'x'. We are not responsible for any type of mistake in data. All pdf files or link of pdf files are collected from various Resources Or sent by Students.
