<PRE><B>Question 1140853</B>
Solution 1 is 175 ml of 3.0 M HCL
:
Solution 2 is 115 ml of 6.0 M HCL
:
Solution 1
:
175/1000 = 0.175 L
:
Moles = molarity * volume
:
Moles = 3 * 0.175 = 0.525 
:
Solution 2
:
115/1000 = 0.115 L
:
Moles = 6 * 0.115 = 0.69
:
Sum the two values to get the total number of moles = 0.525 + 0.69 = 1.215 moles of HCL
:
Sum the volumes of solutions to determine the final volume = 0.175 + 0.115 = 0.29 L
:
*****************************************************************************
Final molarity of the mixed solution = moles / liter = 1.215/0.29 = 4.1897 M
