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.
To do this, it helps to know what a mole is. TL;DR (Too Long; Didn't Read) The mole fraction formula for a solution with containing one or more solutes is: Mole fraction of each solute = Number of moles of that solute divided by the total number of moles of all solutes and the...

Mole Ratio | Definition, Formula & Examples from Chapter 9 / Lesson 2 492K Learn about the mole ratio. Understand the definition of mole ratio, how to find mole ratio in stoichiometry, and see examples of using mole ratio in problems. Related...
Strictly speaking, there is not enough information in just the mole fraction unless you are working in a very dilute solution where you can assume the density of the solution is the same as the density of pure water. If you can do that, then you need to recognise that the mole fraction...
How do you find moles in stoichiometry? How do you do stoichiometry with molarity? How can moles be converted to grams? Define what are moles? How do you do mass to mole stoichiometry? How do you set up a stoichiometry problem?
1. Find mole of H2, N2 and NH3 after equilibrium 2. Calculate the heat. Given that delta H = -91 kJ 3. Calculate K my solution : 3H2 + N2 ---> 2NH3 I 3 9 C -3x -x +2x E 3-3x 9-x 2x then 2x/(2x+12−3x−x) = 1/2 then x = 2 but...

3. Find the Total Volume Add the two volumes together to determine the total volume of the final mixture: 100 ml + 250 ml = 350 ml. 4. Convert to a Percentage Use the formulax= (c÷V) × 100 to convert the concentration (c) and volume (V) of the final solution to a percentage...
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...
