the mole fraction of the solvent = moles of solvent / total moles. Besides, in some cases, the mole number is not given directly. So, you have to find it using the chemical formula of the compounds their weight or their volumes.
The mole fraction of a solute is the ratio of the number of moles of that solute to the total number of moles of solute and solvent in solution. Because it's a ratio of moles to moles, the mole fraction is a dimensionless number, and of course, it's always less than one. Molar ...
Assume one mole of solution so your mole fraction is now simply the moles of solute. Subtract the moles of solute from the total (one mole) to get moles of water. So you now know the moles of solute and the moles of water. Convert moles of water to grams of water using the molar ...

in the text-console of Fluent. (rpgetvar 'species/save-gradients?) can be used to check the current value of this variable. It should return #t (true) now. cheers Hello sir, I was trying to get calculate the gradients of species mass and mole fraction in fluent. I could find the ...
What is molar mass and how do you get the mass?Question:What is molar mass and how do you get the mass?Mole:The amount of substance equivalent to the number of atoms in 12 g of carbon-12, which is 6.023*10^23 atoms. A mole could refer to a simple element or a molecule of compl...
Avogadro's number is 6 x 1023, the number of amu's in one gram, also known as a mole. Avogadro's number is useful to convert the number of atoms to... Learn more about this topic: Moles to Atoms | Formula, Calculation & Avogadro's Number ...
Figure 5b shows that the electrochemical corrosion process results in a reduction in the mole fraction of the alloy matrix. Potential-pH diagrams in Fig. 5c, d reveal that Zn and Cu are immune to dissolution in the matrix, while Al preferentially forms γ-Al2O3 and Mg preferentially remains...
First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on aperiodic table. Then add them together to get the grams per mole for KCl. K = 39.1 g/mol ...
