A chemistry lab experiment requires 33.3 g of silver nitrate. How many grams of a 14.1% by mass solution of silver nitrate should be used?
14.1% by mass means 14.1 g AgNO3/100 g soln.
100 g soln x (33.3/14.1) = ??g soln. Check to see that the answer (236.17 g soln) is 14.1%.
(33.3g/236.17)*100 = 14.1%
236.17 g soln is too many significant figures. You need to adjust that.
