What is the molarity of a solution that contains 1 mol CaCl2 dissolved in 2 L of solution?

molarity= 0.5M

Explanation:

n=CV

n= 1mol, C= ?, V= 2L

1= C×2

C= 0.5M

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
