1.	Which of the statement are true?
Answer» Law of constant compositon is true for all types of compounds. Molar volume of a gas at standard conditions is `22.4 L`. vapour density of a gas is twice of its molecula mass. Atomic masses of most elements are fractional. Solution :a. Not APPLICABLE if the elements exists in different isotopes which may be involved in the FORMATION of compound. b. At 1 atm, `25^(@)C` molar volume `= 22.7 L` c. `Mw = 2 xx VD`, Due ot EXISTANCE of isotopes.
