Concentration refers to the amount of a substance (solute) present in a given volume of solution, typically expressed in units like moles per liter (M). Molecular mass, on the other hand, is the mass of a single molecule of a substance, measured in grams per mole (g/mol). To calculate the concentration of a solution, the molecular mass is used to convert the mass of the solute into moles, enabling a relationship between the quantity of solute and the volume of the solution. Thus, understanding molecular mass is crucial for accurately determining and expressing concentration.

What is a mole used in chemistry as?
Mole is a unit of concentration in SI; a mole is equal to the molecular mass of a compound.
How do you calculate ppm from molecular weight?
To calculate parts per million (ppm) from molecular weight, you first need to know the mass of the substance in grams per mole. Then, you can use the formula: ppm = (mass of substance in grams / total mass of mixture in grams) * 10^6. This will give you the concentration of the substance in parts per million.

How are molecular weights found from titration?
Molecular weights from titration are typically found by titrating a solution of known concentration with a reagent of known concentration. By measuring the volume of titrant required to reach an endpoint, one can determine the moles of titrant reacted. By using the stoichiometry of the chemical reaction, one can then calculate the molecular weight of the compound being titrated.

The molecular mass of water vapour is 18.01528
What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
How can you find the molecular mass of a substance from its mass spectrum?
Obtain the molecular mass by determining the m/z value of the molecular ion peak (rightmost in the spectrum).
What is the molecular mass of sodium chloride?
The molecular mass of sodium chloride is 58,44 (rounded).
