3. (0.750 mol/L) (100.0 mL) = (1.00 mol/L) (x); x = 75.0 mL

4. (0.100 mol/L) (100.0 mL) = (0.250 mol/L) (x)

5a. (18.0 mol/L) (x) = (1.00 mol/L) (2.00 L); x = 0.111 L
5b. (12.0 mol/L) (x) = (1.00 mol/L) (2.00 L)

6. (0.500 mol/L) (x) = (0.150 mol/L) (500.0 mL)

7. (10.0 mol/L) (x) = (0.375 mol/L) (250.0 mL)

8. (1.50 mol/L) (x) = (0.800 mol/L) (2.00 L); x = 1.067 L = 1067 mL

Notice, in problem 8, the multiply by 1000 to get the mL asked for in the problem.
