1.	The percentage of chlorine in the chloride of an element is 44.71%. 158.5 g of this chloride on vaporisation occupies a volume of 22.4 litres at NTP. Calculate the atomic weight and valency of the element.
Answer» Solution :Since 22.4 litres are occupied by 1 MOLE at NTP and WT. of 1 mole is the mol . Wt . In GRAMS , `:.` mol . Wt. of CHLORIDE = 158.5
