How do you calculate ppm from molecular weight?
ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.
What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
Is one mole more concentrated than 3 mole anything?
One or three moles of anything is just different Q U A N T I T I E S of M A T T E R .Concentration is just something else than moles (quantity is not the same as concentration): it can be calculated as moles P E R volume
What happens when the pH is 2?
In the first hand it means it is a fairly strong acid.In a more accurate meaning, the pH is calculated as:-log10 [H3O+]Where [H3O+] means the concentration of hydroxide-ions in the water.So, we know this:-log10 [H3O+] = 2.00So, it is not hard to calculate that the concentration of hydroxide ions is 0,01 g mol-1 .
What is the unit of measurement of force calculated in?
It is calculated in Newtons.
What unkown quantity can be calculated after performing a titration?
Concentration
What is the hydrogen-ion concentration if the acid dissociation constant is 0.000 001 and the acid concentration is 0.01 M?
The concentration in such case is calculated including the H ion concentration contributede by water, So the [H] is .00000001+.0000001
Which type of concentration is calculated when the grams of solute is divided by the grams of the solution and the result is multiplied by 1000000?
ppm
How do you calculate ppm from molecular weight?
ppm is parts per million and thus a concentration. It can not be calculated from molecular weight.
What is the pH of 3.210-9?
pH is defined as the negative log of the concentration of H+ ions in solution. If what you have given is said concentration, the pH can be calculated as follows: pH = -log (3.210E-9) = 8.49
What does square brackets mean in chemistry?
Isn't this the wrong section? >_> Square brackets generally refer to the concentration of whichever element or compound. For example [A] would refer the the concentration of A (generally calculated in moles/Liter or molarity).
How do you find the concentration of sodium chloride in chips?
Chips are boiled, filtered and in the water solution chloride is determined; and from this NaCl content is calculated.
What pH of pka is 5.4?
This question does not make very much sense but it will somewhat be answered. PH is the measurement of a concentration of hydronium ions in a solution. PKA is the measurement of how much is available. If the concentration and pka of a substance is known, the pH can be calculated.
What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
Calculating concentration gradient?
The gradient can be calculated by comparing the solute particles from one solution with another. Distance determines the gradient levels within the solution.
What is the operation principle of a titration?
A solution containing an element to be determined (the concentration being unknown) is titrated (adding a reagent - the titrant) with a standard solution (with a known concentration); knowing the volume of the titrant and the reaction which occur the concentration of the analyte is calculated. Titration is manual (also called volumetry) or potentiometric and is a very common method in analytical chemistry.,
How chlorine is calculated by using chlorotex reagent?
Most of the Chlorotex bottle's has chart on their label, which shows the color appeared by mixing sample and chlorotex, versus concentration.
