Is the makeup of the solution expressed as "percent by mass"? If so, to calculate molarity (or normality), you have to also know the density of the solution
Step 1. Lets say the solution is 14%, and the density is 1.09 g/mL. We can write the following: (14 grams solute/100 grams solution) (1.09 grams solution/ mL solution)
Step 2. Multiplying and cancelling from step 1 gives you 15.26 grams solute / 100 mL solution. Multiplying top and bottom by 10 gives you 152.6 grams solute per liter.
Step 3. Molarity is number of moles per liter. Divide the 152.6 grams of the solute by the forumua weight (or molecular weight) of the solute, and you have the number of moles of solute. This number is therefore the molarity of the solution.
If the solution is "percent by volume", the number you have is number of grams per 100 mL. Multiply by 10, and you have grams per liter. Then divide by the formula weight, and you have the molarity.
mary mixed 2l of an 80% acid solution with 6l of a 20% acid solution. what was the percent of acid in the resulting mixture
true
You dillute it with some more of the same solvent used for the 6 percent solution - pressumably water.
To calculate the Percent to Plan, you can first substitute the variable X for the percent and the variable Y for the Plan, and then you can solve for the end rate of percent to plan easily.
16%
Specific amount of such solution is allow to react with another standard solution as in case of titration process then with the help of formulae normality may be calculated.
Its like when you measure some thing
The normality is o,3.
The normality is 10,8.
for calculating the concentration of solution.
0.08 n
Normality of a solution is defined as the molar concentration divided by an equivalent factor
If the solution volume remains unchanged, the normality will decrease as the NaOH will react with CO2 present in the air. Of course, if the solution volume is not held constant and if the evaporation rate is sufficient to concentrate the solution - it could also increase (effectively raising the normality of the remaining solution).
by bottle method
H2SO4 releases two hydrogen ions into solution. Therefore its Normality is twice its Molarity. Or to answer the question, the molarity is half the normality.
The normality of 98 g of sulfuric acid in 500 mL of solution is 4 N
The normality of a solution is the gram equivalent weight of a solute per liter of solution. For example, 1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles H+ ions.
