PREPARATION OF MOLAR SOLUTIONS

Percent strength is 5%(w/w). The total weight of solution desired is 500g. 5% = 5 g. 100g. 5g x 500 g = 25 g NaCl. 100g. 500 g -25 g = 475g water. Dissolve 25 g of NaCl in 475 g of water. Steps to make a Percent by Weight Solution. Determine the percent and weight of solution desired. Change the percent to a fraction g/100 g. ................
