A colorimeter can be used for that purpose.
A dilute solution contains a relatively small amount of solute per given amount of solvent. Dilution involves adding more solvent to a concentrated solution to reduce the concentration of the solute. This process results in a solution with a lower concentration of solute molecules.
COD in microbiology stands for Chemical Oxygen Demand, which is a measure of the amount of organic compounds in a water sample that can be oxidized by a strong chemical oxidant. It is commonly used to assess water quality and pollution levels in environmental microbiology studies.
The substance that is in the greater amount in a solution is called the solvent. It is typically the dissolving medium that is present in larger quantities compared to the solute.
A solution that has an equal amount of particles is called an isotonic solution. In an isotonic solution, the concentration of solutes is the same inside and outside the cells, leading to no net movement of water across the cell membrane. This allows cells to maintain their shape and size.
The concentration of the solution is measured in microliters per milliliter (u/ml), indicating the amount of solute in a given volume of the solution.

A spectrophotometer is typically used to measure the wavelengths of light absorbed by a solution. This instrument can determine the amount of light of a specific wavelength that is absorbed by the solution, which can provide information about the composition of the solution.
A colorimeter is an instrument used to measure the amount of a chemical substance based on its color. It works by passing light through a sample and measuring the absorbance or transmittance of light, which can then be correlated to the concentration of the substance.
You would use a balance or scale to measure the mass of a dry chemical. This instrument can give you an accurate measurement of the amount of substance present by comparing it to a known reference weight.
A balance or a scale is used to measure the amount of matter in a substance by determining its mass.

A hygrometer is used to measure water vapor in the atmosphere. This instrument can measure humidity levels in the air to determine the amount of water vapor present.
A mole is related to concentration in a chemical solution because it is a unit of measurement that represents the amount of a substance present in a solution. Concentration is the amount of a substance dissolved in a given volume of solution, and moles are used to quantify this amount. By knowing the number of moles of a substance in a solution, one can calculate its concentration.
The instrument used to measure the amount of rain that has fallen is called a rain gauge. It collects and measures the precipitation that accumulates over a specific period of time.
