10. What is the molarity of a solution containing 20 moles of NaCl dissolved in 10 liters of water? 0.5 mol/L
2 mol/L
5 mol/L
10 mol/L

2 mol/L

Explanation:

M=Mol of solute/L. of solution

M=20mol/10L of H2O= 2mol/L

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
