Yes, a 20 percent NEFE acid solution is heavier than a 2 percent KCL water solution because the density of NEFE acid is higher than that of KCL water. The higher concentration of NEFE acid contributes to its increased weight compared to the lower concentration of KCL in water.
NaNO3(ac) + KCl(ac)-----> NaCl(ac) + KNO3(ac)
O2 is oxygen molecule; KCl is potassium chloride
The chemical formula for potassium chloride (KCl) is K + Cl. Since the molar ratio of K to Cl is 1:1, the limiting reactant will determine the amount of KCl produced. In this case, 1 g of Cl is the limiting reactant, so 1 g of KCl will be produced from 2.5 g of K and 1 g of Cl.
The balanced equation for the reaction is: 2KF + Cl2 -> 2KCl + F2
20000 ppm = 2%
Multiply by 10,000: 2 x 10,000 = 20,000 ppm
0.1 percent = 1,000 ppm 1 percent is 10,000 ppm. 2 percent is 20,000 ppm 3 percent is 30,000 ppm 10 percent is 100,000 ppm etc. Take the percent, move the decimal point 4 places to the right, and you have the ppm. You take it from here.
2% is equivalent to 20000ppm

In KCl, there are two elements: potassium (K) and chlorine (Cl).

10,000 ppm Solution Method: 1. A ppm = 1/1,000,000 = 0.000001 2. What you want to know is: how many ppm would = 1% 3. p * .000001 = .01 4. p = .01 / .000001 5. p = 10,000 You could also do it this way: 1. 1% of 1,000,000 = ppm = 10,000 ppm (but that method lacks a clear path to understanding). === previous answer's method: 1%=1/100=1000000/100=10000ppm.
80 x 10-6 = 0.0080 x 10-2 = 0.008%
To prepare a 2 M solution of KCl in 1 liter of water, you would need to dissolve 149.5 grams of KCl. This is because the molar mass of KCl is approximately 74.5 g/mol, and 2 moles of KCl are needed to prepare a 2 M solution in 1 liter of water.
2 ppm means 2 parts per million.
