What is the change in vapor pressure when 73.40 g pentose, C5H10O5, are added to 187.5 g water (H2O) at 298^oK (vapor pressure of pure water at 298^oK = 3.1690 kPa, molar mass of pentose = 150.130 g/mol, molar mass of water = 18.02 g/mol)?
What is the heat capacity of 1.49 moles of liquid water? If the specific heat capacity of water in the liquid state is 1.0cal/g degrees Celcius, calculate the molar heat capacity of water in J/mol degrees Celcius. The specific heat of water is 4.18 \dfrac{J...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
A certain substance has a molar heat of vaporization of 54.2 kJ / mol. How much of the substance is in a sample that requires 80.0 kJ to vapourize? If 1495 J of heat is needed to raise the temperature of a 325 g sample of a metal from 55.0 degrees Cels...
Calculate the molar heat of the solution of RbBr. A chemist wishes to calibrate a bomb calorimeter. So she combusts 5.58 g of 4-pentenoic acid, delta_{combustion}U = -26.77 kJ/g, which causes a temperature change from 23.4 degrees Celsius to 38.9 degrees Celsius. What should the chemist...
water. this prevents the freezing of the radiator during cold seasons. the molar mass of a given solute can be determined from the freezing point depression formula. the degree to which a solute dissociates in a solvent can also be measured with the help of this formula. frequently asked ...
Because entropy, like energy, is an extensive property, a dilute solution of a given substance may well possess a smaller entropy than the same volume of a more concentrated solution, but the entropy per mole of solute (the molar entropy) will of course always increase as the solution becomes...
Mobility is the ability of charged particles to move through a medium as a response to an electric field. The diffusion coefficient is a constant of proportionality between the molar flux (due tomolecular diffusion) and the concentration gradient of chemical species. ...
Then, a thermodynamic-based assessment to quantify how six individual fuel properties can affect efficiency in SI engines is performed: research octane number, octane sensitivity, latent heat of vaporization, laminar flame speed, particulate matter index, and catalyst light-off temperature. The relative...
