$\huge \underbrace \mathfrak \red{Answer}$

28%

Step-by-step explanation:

mass of solute(KBr) = 3.73g

mass of solvent(H2O) = 131g

mass of solution = mass of solute + mass of solvent

= 3.73 + 131

= 134.73g

$\sf \large {mass \: percentage = (mass \: of \: solute)/(mass \: of \: solvent) * 100} \\ \\ \sf mass \: percentage = (3.73)/(134.73) * 100 \\ \\ \sf mass \: percentage = 0.028 * 100 \\ \\ \sf mass \: percentage = 28\%$
