Answer:
0.531 mole/L = 0.531M
Explanation:
What NaCl concentration results when 294 mL of a 0.750 M NaCl solution is mixed with 637 mL of a 0.430 M NaCl solution?
294 ml X 0.75 moles/1000ml=0,294X0.750 = 0.2205 moles
637 ml X 0.430 moles/1000ml = 0.637 X 0.430= 0.2739 moles
0.2205 + 0.2739 = 0.4944 moles
this is distributed over 294 ml + 637 ml= 931ml
with a concentration of 0.4944 moles/0.931L or 0.531 mole/L = 0.531M
