1. The problem statement, all variables and given/known data

Simplified....

2.0 mL .20M "X" added to 9ml making an 11mL soln.

What would be the concentration of "X"?

2. Relevant equations

M= molarity=moles/liters

3. The attempt at a solution

2.0ml=.002L x .2M= .0004 moles/.011L=.0363636...M "X"

Right?...

Thanks,

Warren
