138 g NaCl
1.10 L= 1100mL
1100mL x 1.08g/mL = 1188 grams TOTAL
138/1188 x 100 = 11.6%
The concentration is 1 mol/L or 5,611 g KOH/100 mL solution.
The molality is 5,54.
The salt solution in the bucket is 10% of the salt solution in the bag. The bagged solution has a higher density than the bucket solution; therefore, the bagged solution will most likely fall to the bottom of the bucket as the bucket water is displaced above it -- assuming there is no air in the bag, the density of the bag material is negligible, and the salt is fully dissolved in the water. Details: = The solution in the bucket is 0.3% while the solution is the bag is 3%. Thus, the solution in the bucket has less concentration of salt than the solution in the bag. Hence, the solution in the bucket is hypotonic to the solution in the bag.

Diluted Ammonia solution can be prepared by diluted strong ammonia solution with the appropriate quantity of purified water.
Formalin is 40% solution of formaldehyde not an acid.
100 g of solution containing 50 g of NaOH.
40% aqueous solution of formaldehyde is known as Formalin.
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
If the density is 1.0 g/ml, one liter of the solution will weigh 1000 grams. 3.0 % of this mass or 30 grams of it is constituted of H2O2. The molar mass of H2O2 is 2 (1.008 + 15.999) = 34.014. The molarity of this solution is therefore 30/34.014 = 0.88, to the justified number of significant digits.

The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
