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...
The atomic mass of W-188 atoms is 187.958489 AMU / 1 atom. note the #'s are the same note the units are different... g / 6.022x10^23 atoms... vs... AMU / 1 atom why are the #'s the same while the units are so different? it's because of how moles of atoms (6.022x10^23...
Moles A unit used to measure the amount of a substance, where 1 mole contains Avogadro's number of entities. Ideal Gases Gases that behave according to the ideal-gas equation under low pressure conditions. Avogadro's Number 6.022 x 10^23, the number of atoms or molecules in 1 mole of a...
The pH scale is logarithmic and shows the solution’s concentration of hydrogen ions inversely. More specifically, the pH of the solution is the negative logarithm to the base 10 of its hydrogen ion concentration in moles per litre. The pH scale can be traced to a series of standard solution...
millimoles / liter and postprandial blood glucose levels above 11.1 millimoles / liter, establishing the absence of a decrease in blood glucose levels and the necessary values of glycated hemoglobin after prescribing insulin therapy, followed by direct calculation of the insulin dose, in which the ...
I used 0.2g of salicylic acid, 1.45x10-3 moles. So dH is -6013J /1.45x10-3 mol => -4147 kJ/mol. The result is -3020 kJ/mol. This is too much error.. I hope this is clear now, what do you think I've done wrong?
Calculating Reaction Rates Chemical reaction rates are the rates of change in concentrations or amounts of either reactants or products. For changes in amounts, the units can be one of mol/s, g/s, lb/s, kg/day etc. For changes in concentrations, the units can be one of mol/(L s)...
A dynamical model for such problem is developed for the first time by using the laws of thermodynamics and Onsager's reciprocal principle. This model consists of the evolutionary equations for moles and volume, and it can characterize the evolutionary process from a non-equilibrium state to an ...
