1 Answer. Find the total mass of the nitric acid HNO3 Then divide the mass of each atom by the total mass to find the percentage.
What is the mass percent of HNO3?
Elemental composition of HNO3
How do you make 5% HNO3 solution?
CAREFULLY add 5 mL of concentrated nitric acid to both tubes and heat them in the dry block heater at 60 C for 1 hr under a hood. Quantitatively transfer the contents of each test tube into a separate 100-mL volumetric flask and bring up to volume with MP water (solution will now be 5% (v/v) HNO3).
What is the mass of a concentrated solution of nitric acid?
A concentrated solution of nitric acid is 68% HNO 3 by mass which means that there are 68 grams HNO 3 per 100 grams of solution.
What is the mass of a 4.00 NaOH solution?
The percentage mass of NaOH in the solution = 4.00 %. The mass of NaOH = 15.0 g.
What is the formula of brine solution?
|Synonyms||Brine NaCl water HCl NaOH sodium chloride water water sodium chloride More…|
|Molecular Weight||76.46 g/mol|
|Component Compounds||CID 962 (Water) CID 313 (Hydrochloric acid) CID 5360545 (Sodium)|
How do you calculate salt solution?
To make a salt solution by weight percent (w/v), you apply the formula w/v = (mass of solute ÷ volume of solution) × 100. The density of water is 1 gram per milliliter (g/ml) which means 1 milliliter of water weighs 1 gram.
What is the dissolving substance in a solution?
The solute is the substance that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with many different types and forms of solutes and solvents.
