How to calculate the no of ion in one mole
Answers
Number of ions = moles × Avogadro number × ions in the molecule
Hope it helps you
Answer:
it is the basic of mole concept the no. Of particles i.e. ion,atom, subatomic particle present in one mole of any substance is always equal to avogadro number I.e. equal to 6.023*10^23
Explanation:
You should multiply by Avogadro's number 6.022×1023 instead of dividing by it. To make sure you always use a conversion factor (Avogadro's number is a conversion factor between moles and numbers) correctly, you need to think about units.
Step 1 - What are the units of the answer?
You want to find the number of ions. The units of the answer is number.
Step 2 - What are the units of the quantities you were given?
You were given 0.0585 moles of Al3+. The units you are given is "moles".
Step 3 - What are the units of the conversion factor?
Avogadro's number (with units) is 6.022×1023 mol−1. The units of Avogadro's number are "number per mole".
Step 4 - Set up the problem so that units cancel and you are left with only the units you need.
Multiplying by Avogadro's number
mol×numbermol=number
The "moles" units cancel, leaving you with "number".
Dividing by Avogadro's number
molnumbermol=mol×molnumber=mol2number
The units do not cancel appropriately, leaving us with units that do not match the desired outcome. This approach is an application of dimensional analysis commonly called the factor-label method. With practice and conscientious use of this method, you should not make unit conversion errors.
Step 5 - Check to see if your answer makes sense.
0.0585 moles is about 120 of a mole (or one half of one tenth). Your answer should be about 120 of Avogadro's number
