what is the molarity of a solution containing 15.6 grams of kcl in 274ml's of solution

39x1=39

35.5x1=35.5

74.5 molar mass   15.6/74.5=0.21 moles

274ml/1000=0.274 L  

0.21/0.274=0.77

is this correct


15.6 grams of kcl in 274ml's

 molarity = moles of solute / volume of solution in l

274ml/1000=0.274 L  good

 

74.5 molar mass   15.6/74.5=0.21 moles  good

0.21/0.274          good
