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 %.
NaCl contain 39,66583 % sodium and 60,33417 % chlorine.
20g NaHCO3/ (600g H2O + 20g NaHCO3) x 100 = 3.225
Sodium chloride contain 39,66 % sodium.
The answer is 16,7 %.
The answer is 12,5 %.
The concentration is also 36,9 g/L.
This concentration is 11,1 %.

60 grams
usually around 800 grams
5 kg is greater (it is equal to 5000g)
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.
600g
NO
600g = 21.2oz
6000
600 grams is 21.16 ounces.
