Treatment of 1.385 g of an unknown metal M with an excess of aqueous HCl evolved a gas that was found to have a volume of 382.6mL at 20.0 degrees Celsius and 755 mm Hg pressure. Heating there action mixture to evaporate the water and remaining HCL then gavea white crystalline compound, MCl. After dissolving the compound in25.0g of water, the melting point of the resulting solution was-3.53 degrees Celsius
