Suppose 2.34 moles of glycine (an amino acid) is dissolved in 475ml of water and then brought up to a final volume of 655ml with water. What is the molarity of this solution?

THIS IS SIMPLE QUESTION ALL DATA IS GIVEN JUST CALCULATE THE MOLARITY USING FORMULA AND THE APPLY DILUTION FORMULA M1V1 = M2V2
WHERE V2=TOTAL VOLUME = 655 mL V1=475 mL1 M1= 4.92 M (CALCULATED)
NOW PUT IN DILUTION FORMULA AND EVALUATE M2 COMES OUT TO BE 3.57M
