Explanation:
I think 5.50 M x 35.0 mL x molar mass of RbOH = mass (g)
The fact that the unit is supposed to be in percent makes me think it is referring to percent mass. To find percent mass you need to find find the divide the mass of solute by the total mass of solution and than multiply that by 100%.
%mass=(50g/300g)x100%
%mass=0.167%
I hope this helps.
