Answer:
molecules Cl- = 3.01 E23 molecules
Explanation:
molecules Cl- = 0.50 mol CL- * ( 6.02 E23 molecules/ mol ) = 3.01 E 23 molecules
Answer:
So the number of molecules in 0.50 moles of chlorine are 3.011 ×10²³molecules
Explanation:
Given data:
Number of moles = 0.50 mol
Number of molecules = ?
Solution:
To solve this problem we will use the Avogadro number.
The number 6.022×10²³ is called Avogadro number and it is the number of atoms in one mole of substance or number molecules in one mole of compound.
While we have to find the molecules of chlorine in 0.50 moles.
35.5 g of chlorine = 1 mole of Cl = 6.022×10²³ molecules
For 0.50 moles:
0.50 × 6.022×10²³ = 3.011 ×10²³molecules
So the number of molecules in 0.50 moles of chlorine are
3.011 ×10²³molecules.
