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.

The normality of benzoic acid depends on its concentration in solution and its molecular weight. To calculate normality, you need the molarity of the solution and the number of equivalents of acid per mole of benzoic acid. Normality is equal to Molarity times Equivalent factor.
To calculate normality using specific gravity, you would first determine the concentration of a solution in g/mL. Then, divide the concentration by the equivalent weight of the solute to get the number of equivalents per liter. This value represents normality.
To find the normality of a solution, you need to know the molarity and whether the solution is monoprotic or polyprotic. Since fuming HCl is typically monoprotic (one hydrogen per molecule), you can assume the normality is equal to the molarity. Therefore, the normality of a 37% fuming HCl solution is approximately 11.1 N (since 37% is roughly 11.1 M HCl).

To prepare 1N H2SO4 from 95% H2SO4, you would first need to dilute the 95% H2SO4 with water by adding the appropriate amount of water to achieve the desired concentration. To calculate the volume of 95% H2SO4 needed to make 1N solution, you need to use the formula: (Normality of stock solution) * (Volume of stock solution) = (Normality of diluted solution) * (Volume of diluted solution). Adjust the volumes accordingly to prepare the desired 1N solution.
The normality of an NaOH solution will remain the same if exposed to air for prolonged periods because normality is a measure of concentration. However, the concentration of the solution may change if water evaporates from the solution, leading to an increase in the normality.
Normality (N) is calculated by dividing the molarity (M) of a solution by the equivalent factor (EF) of the solute. The equivalent factor is determined by the number of ions produced or reacted per molecule of solute. The formula for calculating normality is N = M x EF.
To calculate the normality of NaOH for a 1:1 molar ratio, you can use the formula: Normality = Molarity x Number of equivalents. Since NaOH is a monoprotic base, it provides one equivalent per mole. Therefore, for a solution of NaOH with a molarity of 1 M, the normality would be 1 N.
The normality is o,3.
Normality is the number of gram equivalents of solute per liter of solution.N = [ ( m ) / ( M ) ( Z ) ] [ 1000 / V in mL ]where Z represents the number of H+ ions that the one molecule of the solute is capableof releasing or reacting with. For HCl, Z = 1 .N = [ ( 3.65 g ) / ( 36.458 g / mol ) ( 1 ) ] [ 1000 mL / 1000 mL )N = 0.100 N
The normality of a solution is a measure of the concentration of a solute in a solution. For HCl (hydrochloric acid), the normality would depend on the concentration of the HCl solution. For example, a 1 M (molar) solution of HCl would be 1 N (normal).
To determine the normality of a sodium hypochlorite solution containing 4% active chlorine, you first need to calculate the molarity of the solution based on the percentage of active chlorine. Once you have the molarity, you can convert it to normality based on the reaction of sodium hypochlorite.
