Not too great with chemistry :/... Any help/guidance is greatly appreciated.

1. Observe the following reaction:
NaOH + HCl → NaCl + H2O
If 8.00 mL of HCl requires 7.52 mL of 0.10 M NaOH to consume the HCl (or titrate to completion), what is the concentration of HCl?

2. A 1 cm cuvette was filled with a solution which contains only a solute with a molar absorbtivity coefficient of 4800 M-1cm-1 and solvent. After blanking with the pure solvent the absorbance of the solution is 0.543. What is the concentration of the solution?

1. M1xV1 = M2xV2
Can you do that?

2. absorbance x absorbtivity constant
