Question

How do you calculate mole fraction of solute?

Answer 1

Hint: Mole fraction addresses the number of atoms of a specific segment in a blend separated by the all-out number of moles in the given combination. It's a method of communicating the grouping of an answer.

Complete answer:
The mole fraction of solute is:
moles of solute divided by total moles of solute and solvent
Example 1 0.100 mole of NaCl is dissolved into 100.0 grams of pure $H_2O$. What is the mole fraction of NaCl?
We will calculate the number of moles of water (solvent)
$\dfrac{100.0g}{18.0}$gmol - 1 = 5.56 mol of $H_2O$
Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66mo total
Mole fraction ofNaCl = $\dfrac{0.100mol}{5.66mol }= 0.018$
What is the mole fraction of the $H_2O$
$\dfrac{5.56mol}{5.66mol }= 0.982 $

Sulfur dioxide is a side-effect of numerous cycles, both normal and human-made. Gigantic measures of this gas are delivered during volcanic emissions. People produce sulfur dioxide by consuming coal. The gas has a cooling impact when in the climate by reflecting daylight moving in an opposite direction from the earth. In any case, sulfur dioxide is likewise a segment of brown haze and corrosive downpour, the two of which are destructive to the climate.
Numerous endeavors have been made to diminish \[S{O_2}\] levels to bring down corrosive downpour creation. An unexpected confusion: as we bring down the centralization of this gas in the air, we bring down its capacity to cool, and afterward we have dangerous atmospheric devotion concerns.

Note: Recorded as a hard copy the electron arrangement for Sulfur the initial two electrons will go during the 1s orbital. Since 1s can just hold two electrons the following 2 electrons for sulfur go during the 2s orbital. The following six electrons will go in the 2p orbital.
