Arun has prepared 0.01% (by mass) solution of sodium chloride in water. Which of the following correctly represents the composition of the solutions?
(a) 1.00 g of NaCl + 100g of water
(b) 0.11g of NaCl + 100g of water
(c) 0.0l g of NaCl + 99.99g of water
(d) 0.10 g of NaCl + 99.90g of water
(c) Here,
which is equal to the percentage of sodium chloride in water prepared by Arun. So, option (c) is correct.
In option (a), mass% = 
In option (b), mass% = 
In option (d), mass% = 
Thus, other three representations are incorrect.
