To calculate the number of molecules in 1cm3 of an ideal gas at 27∘C and a pressure of 10mm of mercury, we can follow these steps: Step 1: Convert the pressure from mm of mercury to dynes per cm²The pressure given is 10mm Hg. We know that:- The density of mercury is 13.6g...
We can calculate the number of molecules in a sample from the amount of samples given. Initially, we have to calculate the number of moles present in the given sample.1 mol of any sample contains6.022×1023molecules. Thus, we can calculate the number of molecules by multiplying the number...
Calculate number of moles if a sample contains 1.81×1022molecules. Number of Moles: There is a very obvious calculation between the Avogadro constant and molecules for finding or determining the moles. A required mathematical formula for this is shown below. ...

A mole is 6.02 x 10 to the 23 particles (atoms or molecules, depending on the substance studied). First, take the atomic mass for each element as given in the periodic table, multiply it by the number of atoms of that element in the compound, and sum the results for all elements in...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
Calculate the van't Hoff factor (i) for CuCl_2, which is the number of particles the solute dissociates into in solution. Use the freezing point depression formula:ΔTf=i⋅Kf⋅mto find the change in freezing point, whe...
tension of the program is available for systems with a large number of molecules in the solution. The geometry of the molecules (ions) A and B in the calculations remains unchanged. During the calculations the position of molecule A is fixed spatially whereas B participates in the MC process ...
