Answer: Where are the answers?
Explanation:
Answer:
The molarity of the solution is: 2,167 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
3,6 L solution ------- 7,8 moles of MgCl2
1 L solution -----------x= (1 L solution x 7,8 moles of MgCl2)/3,6 L solution
x=2,167 moles of MgCl2 ---> <em>The solution is 2, 167 M</em>
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
