Calculate the number of moles of O atoms in 13.27 g Mn(NO3)2. Hi I did this question and it seemed pretty easy but there is this online assignment I am...
A model of hydrate formation in multicomponent gas–liquid water or ice systems including the exo- and endothermic processes has been suggested. Based on this model, a method for calculating the molecular and energy parameters such as the hydration number, amount of moles of hydrate, amount of ...
they give you the molecular weights of each component, and you can find the molecular weight of the mixture by just adding the molecular weights. since the masses are in grams, and moelcular weight is in g/mol, if you divide the mass by molecular weight you get just mo...
XB = 0.009174 the mole fraction of the solute unsure of what ?T is we were giving the equation ?T = Kf mB ?T = the freezing point depression Kf = the cryoscopic constant of the solvent mB= the molarity of the solution, or the number of moles of solute per kilogram of solvent. ...
Let ni be the number of moles in phase i (unit: moles)Let VM,L be the molar volume of liquid water (unit: m3/mol)Consider Vapour Phase,PVvapour = nvapourRTnvapour = Mass / (Molar Mass) = 100X/MPVvapour = (100X/M)RT = 100XRT/MVvapour = 100XRT/(PM) (Equation 1)Consider ...
As another example, 70% v/v rubbing alcohol may be prepared by taking 700 ml of isopropyl alcohol and adding sufficient water to obtain 1000 ml of solution (which will not be 300 ml). Mole Fraction (X) This is the number of moles of a compound divided by the total number of mole...
There will be 8 grams of excess H2gas at the end of the reaction. There is enough information to answer the question. The limiting reactant was O2. There will be 8 grams H2remaining. There will be 108 grams H2O formed by the reaction. ...
Capillary pressure can significantly affect the phase properties and flow of liquid-gas fluids in porous media, and thus, the phase equilibrium calculation incorporating capillary pressure is crucial to simulate such problems accurately. Recently, the phase equilibrium calculation at specified moles, ...
Additionally, changes in pressure can be accounted for by using the ideal gas law, PV = nRT, where n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. Are there any limitations to using q, w, H, and U in a practical setting?
