Answer 3

9.45 g C2H6O in 66.1 g H2O
116 g KCl in 588 g H2O
31.3 mg KNO3 in 2.44 g H2O

Answer 4

concentration by mass percent\[\frac{ mass of solute}{mass of solution} \times 100\] in ur question,
mass of solute=110g
mass of solution=mass of water + mass of KCl

Answer 5

But for there don't you have to do a balanced equation first? Or am I thinking about a different chemistry topic?
