If You do that experiment under standard conditions, the weight of 100 ml water will be 100 g. The mass of the total system is 120 g in that case and the NaCl contributes to it with 20/120*100 mass percent.
Thus the answer is 16.67 %.

60 grams
When 24g of sugar dissolves in 576g of water, the total mass of the solution remains at 600g (24g + 576g). The mass of the sugar does not change when it dissolves, it simply disperses throughout the water.
usually around 800 grams
600g is equivalent to approximately 1.32 pounds.
600 grams is 21.16 ounces.
0.6kg = 600g
40 to 50 grams (source a uk butcher's site that offers a 600g pack containing on average 12 kidneys and another site that offers 160g packs of 4)
Still 600g unless you take it more than once. If you take 600g once a year in 10 years time it will be 6000g aka 6kg. I have a feeling you missed adding something to the question.

60g = 2.116oz
