[5] Synthesis [ edit] Krypton difluoride can be synthesized using many different methods including electrical discharge, photoionization, hot wire, and proton bombardment. The product can be stored at −78 °C without decomposition. [6]
WebReferring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable “ballpark” estimate of the number of moles would be slightly greater than 0.1 mol. WebWe will do this in two steps: convert the mass of AlCl3to moles and then use the balanced chemical equation to find the number of moles of HCl formed. The molar mass of AlCl3is 133.33 g/mol, which we have to invert to get the appropriate conversion factor: Now we can use this quantity to determine the number of moles of HCl that will form.
WebThe actual masses of atoms, molecules and ions are too small to be useful in calculations. For this reason, chemical amounts are measured in moles. The mole is a unit.
