Most of the time they will give the actual yield in the problem. If it is not given, then they probably will not ask for you to calculate the precent yield unless other information is given.
First things first, you must find out how many grams on KNO3 are on 510g. So to do that, you must divide 5.45 by 100 which gets you 0.0545. Then you multiply that by 510g. This tells you how many grams of KNO3 is in the 510g solution which is 27.8g . So then for the second part of the problem, you w...
114 and 114. have the same number of sig figs but adding the "." does seem a little redundant so I'd say stick with 114. But 114.0 is not the same as 114 because it has 4 sig figs.
