Treatment of 1.385g of an unknown metal M with an excess ofaqu. HCL evolved a gas that was found to have a volume of 382.6mLat 20.0 C and 755 mm Hg pressure. Heating the reaction m ixture to evaporate the water and remaining HCL then gave a white crystalline compound, MClx. After dissolving the compound in 25g of water, themelting point of the resulting solution was -3.53 C

a) How many moles of H2 gas are evolved?

b) What mass of MClx is formed?

c) What is the molality of particles (ions) in the solution ofMCLx?

d) How many moles of ions are in solution?

e) What are the formula and molecular mass of MClx?

f) What is the identity of the metal M?
