Dear chemists..please help me with this.?

calculate the density, %w/w, %w/v, ppm, and ppbof a 0.0438M NaCl solution. Also, compute for its normality if it is used as a complexing agent for Al3+ as shown by the reaction below: (MM NaCl= 58. 44g/mol)

Al3+(aq) + 4Cl-(aq) -> [AlCl4]- (aq)

%w/w = 0.0438*58.5/100 and likewise.
