The #"mass"/"mass"# "#%"# concentration of a solution is calculated by dividing the mass of solute by the mass of solution then multiplying times 100%.

#"mass"/"mass"# #"%"# = #"mass of solute"/"mass of solution"# x #"100%"#

Given:
mass of solute (#"SrCl"_2#) = 6.50 g
mass of solution = 250.0 g

Unknown:
% concentration

Solution:

#"mass"/"mass"# % = #"6.50 g SrCl"_2"/"250.0"# #"g"# #"solution"# x #"100%"# = #"2.6%"#

Answer:
The mass/mass % concentration of the solution is 2.6%.
