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...
Molalityis the number of moles of solute per kilogram of solvent. Because the density of water at 25°C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an...
We are given the molar mass of aluminum. We can see that we first need to calculate the number of moles of aluminum produced. And using this value and the molar mass, we can then determine the mass. We are not given the number of moles of aluminum, but we are given other data. We...
Re: Calculating number of ions « Reply #3 on: July 25, 2008, 09:44:55 AM » hey,do you know about this formula?No. of particles or ions = no of moles x Avogadro's constantAvogadro's constant = 6.02 x 10^23 Logged No matters what results are waiting for us, it's nothin...
φ=NM1/2Q1/2, detonation velocities by the equationD=Aφ1/2(1+Bρ0), A=1.01, B=1.30.Nis the number of moles of gaseous detonation products per gram of explosive,Mis the average weight of these gases,Qis the chemical energy of the detonation reaction(ΔH0per gram), andρ0is the ...
The empirical formula of a compound is determined by its percent composition. The mass of the given compound is assumed to be 100. Hence, the mass percent is taken as the mass (in g) of that element. The mass is then converted into the number of moles. The resultant values are...
The method is based on assessment of the enthalpy change (螖 H ) of feedstock components and reaction products, with the formation enthalpies of molecules being presented as a linear function of the number of moles of the elements C, H, N, O, and S. The results of computational study ...
at 300k, 6.00 moles of pcl 5 kept in 1 l closed reaction vessel was allowed to attain equilibrium. you are required to find the composition of the mixture at equilibrium. given that k c for the reaction is 1. step1 : write the balanced equation for the reaction for which the ...
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?
What is the maximum possible number of moles of Zn plated? 3. A 1.0 A current is used to electroplate {eq}Ni^{2+} {/eq} from solution into Ni. What is the maximum rate of Ni production? 4. A 5.0 A current is is applied for 1.0 hr to electroplate {eq}Au^{3+} {/eq} ...
