When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?
