Measure out any volume of water in a pre-weighed beaker (or container...sigh*). Then bake the beaker in a warm oven until all the water evaporates and the beaker is dry. Reweigh the beaker . Subtract the original weight of the empty beaker from the new weight. You now have the weight of the salt present in your original amount of water !
NOTE: If you are using ocean water this may be imprecise due to other contaminants remaining in the beaker. AKA you are not JUST weighing salt at the end.

What else can I help you with?
How could you find the salt concentration of salt water?
1. By determination of sodium and chlorine. 2. Using a salinometer.
Which instrument can use to measure the concentration of salt water?
We can use a conductivity meter (salinometer), a densimeter or for exact results analytical chemistry instruments for the determination of sodium.
How is concentration of salt measured?
The concentration of salt in water is measured with a salinometer or by the chemical determination of chlorine or sodium.
How you find out how much salt there in a sample of water?
1. Using an instrument called salinometer. 2. A more accurate method: chemical determination of sodium and chlorine.
How do you detect sodium chloride solids in water?
Methods are: - by determination of sodium - by determination of chlorine - using a salinometer
Why the sea water is diluted in flame photometry?
Sea water is diluted before flame photometry to reduce the salt content, which can interfere with the measurement of specific elements. The high salt concentration in sea water can lead to high background noise and inaccurate readings, so dilution is necessary to obtain accurate results for trace metal analysis.
What instrument using when measuring your water bill?
barometer
Why addition of water to the vinegar does not effect the determination of its concentration in titration?
Yes, it DOES effect the concentration (mol per litre). This is because the volume (of solution, litres) has changed, when diluting, but not the total quantity (just moles of 'reacting' vinegar in the titration).
How are you able to find the concentration of a chemical in water?
The concentration of a chemical in water can be found using various methods such as spectrophotometry, titration, or chromatography. These methods involve measuring the absorbance, volume, or separation of the chemical in water to calculate its concentration. accurate measurements and proper calibration are essential for determining the concentration of a chemical in water.
Why addition of water to vinegar does not effect the determination of its concentration in titration?
Yes, it DOES effect the concentration (mol per litre). This is because the volume (of solution, litres) has changed, when diluting, but not the total quantity (just moles of 'reacting' vinegar in the titration).
The relative concentration of water molecules in a liquid sample is called?
specific gravitythe relative concentration of water molecules in a liquid sample. A clinical lab test that measures specific gravity in a sample of urine is made to evaluate filtration and water reasborption in the kidneys, using a urinometer.
What are the answers to chem lab 5- density determination?
2. Using water displacement since it works for any kind of shape.
