Homework Statement The vapour density of a sample of N2O4 gas is 35. What per cent of N2O4 molecules are dissociated inNO2? Homework Equations molar mass = 2 * Vapour Density The Attempt at a Solution I tried to solve this question this way, Let the initial number of moles of N2O4=a ...
Volume, moles, density, molar mass =>separation of molecules Homework Statement I am doing an exercise from my physics book right now. I am given: 1 molecule of hydrogen corresponds to 3.7x10^-26 m^3 1 molecule of led corresponds to 2.99x10^-29 m^3 the ratio of these volumes is 1.22...
What is the mass of a liquid with a density of 2.12 g/ml and a volume of 53.0 ml? What are the differences between cellular respiration and photosynthesis? What is the conversion factor from km to ft? What is an example of a chemical equation?
Write a balanced chemical equation for this process. If 10 mol of hydrogen reacted with oxygen, what volume of liquid water could be produced?9. You sometimes hear in a medical show on TV something like “Give the patient 200 cc’s of medicine X”. Given that a litre is a cubic ...
If you were given the density and volume of pure material you could calculate the volume of another material in that equation if you know its density. Notice that the density must be inverted to cancel the units properly if you want the volume to find. If you need to find the density, ...
The mobility is obtained from diffusion coefficients by relating the gradient of chemical potential to the gradient of molar density. The evolution equation for moles of each component is derived using the discretization of diffusion equations, while the volume evolution equation is constructed based on...

You need to multiply the molar mass of the substance by the number of moles: As you can see, the most difficult task here isfinding out the molar mass of the substance. The molar mass of the substance Themolar massis a physical property defined as the mass of a given substance (chemical...
the trigeminal nerve serves both the relatively small whisker pad as well as the mechanosensitive Eimer's organs which cover the glabrous skin of the nose. Moles exhibit a range of Eimer's organ density, with none on the Eastern moles27 and approximately 25,000 organs in the facial appendages...
How many grams of tin will occupy 5.5 L if it has a density of 7.265 g/cm^3? While balancing a chemical equation, how can one decide which elements to balance first? How do you synthetically fuse atoms together? Is there a fixed number of orbitals for each atom? What is the differenc...
