Problem 63
A 1.42-g sample of a pure compound, with formula M2SO4, was dissolved in water and treated with an excess of aqueous calcium chloride, resulting in the precipitation of all the sulfate ions as calcium sulfate. The precipitate was collected, dried, and found to weigh 1.36 g. Determine the atomic mass of M, and identify M
Step-by-Step Solution:
Step 1 of 3
Gases - System: energy (Temperature); intensity (pressure); composition (mole fraction) - Mole fraction is proportional to partial pressure n - χ = component component n total - Ideal gas law: PV = R nT - There are no attractive molecules in any gas system lacking significant attraction - Temperature is proportional to energy - Composition breaks down the identity of the system - The total pressure is 1.00atm
