Chemists can use a mass spectrometer to determine the elemental composition of any substance; they also have various other analytical techniques available.
Solid gold is typically measured in karats, which represent the purity of the gold. Pure gold is 24 karats, so solid gold can have a karat value ranging from 10 karats (41.7% gold) to 24 karats (100% gold), depending on the level of purity.
No. Melted or solid, it's still the same weight and purity, which is what decides the value. Melted would only be worth a tiny bit more to someone who is waiting to cast it into moulds.
The percentage purity of borax can vary depending on the specific product and manufacturer. Typically, commercial borax products have a purity level of around 95-99%. It is important to check the product label or manufacturer's specifications to determine the exact percentage purity.
One common method to check the purity of hydrogen gas is through gas chromatography, where the components of the gas mixture are separated and identified. In addition, purity can be verified using specific sensors or detectors designed to measure the presence of impurities in the gas. It's important to use calibrated equipment and follow proper procedures to ensure accurate results.
To check the purity of toluene, you can use techniques such as gas chromatography or infrared spectroscopy to analyze its composition and identify any impurities present. You can also compare the experimental data with the known properties of pure toluene to assess its purity. Additionally, conducting a simple distillation can help separate out impurities from the toluene sample.
Sometime it is needed to check purity of a liquid, to check metal content of a liquid.
Your answer depends on the purpose of your test.
Chemical analysis is used to test the purity of materials. We know today a very great number of analysis methods.

Purity rings are available in many jewelry stores in malls around the country. Check with Zales, Kay Jewelers and other fine outlets.

Alcohol purity can be checked using a hydrometer to measure the specific gravity of the alcohol. Another method is gas chromatography, which can analyze the components of the alcohol to determine its purity. Additionally, distillation techniques can be used to separate impurities from the alcohol.
