You are diluting 6.00 M solution from 50 to 500 mL; therefore, the final concn is
6.00 x (50/500) = 0.600 M
There is another, more fundamental way of doing this.
1. How many moles do you have in the 6.00 M solution. moles = M x L = 6.00 x 0.05 L = 0.300 moles.
2. How many moles do you have in the diluted solution? Of course, 0.300 moles.
3. What is the concn? The definition, remember, is M = moles/L; therefore, M = 0.300 moles/0.5 L = 0.600 M.
