If 25.0mL of sodium nitrate solution (0.100mol/L) is added to 10.0mL of sodium carbonate solution (0.150 mol/L), what is the concentration of sodium ions in the resulting mixture? Assume the volumes are additive.

• Chemistry -

moles + moles = total moles.
volume + volume = total volume.
M = total moles/total volume.

• Chemistry -

Those aren't mole, those are concentraiton

Hello, i am still needing help

• Chemistry -

Hello yourself. I know those are not moles. I told you how to work the problem. Do you know how to get moles? Convert each to moles. Find moles Na in each. Add everything together to get final moles etc etc. Let me know if you still need help but tell me what you don't understand.
