The Question: What happens to the Molarity if you add more water? The POGIL Answer: The Formula they hide: ( M_1V_1 = M_2V_2 ) Example: If you have 1 L of 6 M HCl and add 1 L of water (total volume 2 L): ( 6M \times 1L = M_2 \times 2L ) => ( M_2 = 3M ).
The Question: If you have 1 mole of NaCl dissolved in 0.5 L of water, what is the molarity? The Math: ( M = 1.0 \text mol / 0.5 \text L = 2.0 \text M ) The Sticking Point: Students forget to convert mL to L. If the volume is 250 mL, you must divide by 1000 to get 0.25 L.
