In this case, a
Since solutions are homogeneous mixtures, i.e. the have the same composition throughout, you can use the percent concentration by mass as a conversion factor to determine the mass of solute present in your sample
#55.491 color(red)(cancel(color(black)("g solution"))) * "1.67 g KCl"/(100color(red)(cancel(color(black)("g solution")))) = color(darkgreen)(ul(color(black)("0.927 g KCl")))#
The answer is rounded to three sig figs, the number of sig figs you have for the solution's percent concentration.
