the molar mass
1 mole = xxx grams based on the chemical formula
Ex: CO2 ... the Atomic Mass of carbon is 12, and the atomic mass of oxygen is 16
but the molar mass = (1 x 12) + (2 x 16) because of the number of atoms of each in the formula. molar mass = 44. so 1 mole = 44 grams ... turn this fact into a conversion factor. 44g / 1mole is the conversion factor to convert moles of carbon dioxide into mass (grams). Each substance will have a different molar mass, so a different conversion factor.

Is molar mass the conversion factor in stoichiometry?
While molar mass is not a conversion factor itself in stoichiometry, it plays a crucial role in converting between grams and moles of a substance. Molar mass is used to convert the mass of a substance to moles, enabling the stoichiometry calculations that involve mole ratios in chemical reactions.
What conversion factor for sodium is used to change mass to moles is?
The conversion factor for sodium is its molar mass, which is ~22.99 g/mol. To convert mass to moles, you divide the given mass by the molar mass of sodium.
Why cant molar mass be used as a conversion factor?
Molar mass is a property of a single substance and is not inherently a conversion factor. To use it as a conversion factor, you would need to relate it to other units (e.g., grams to moles) through Avogadro's number. It serves as a bridge between the macroscopic scale (mass) and the microscopic scale (number of particles) in chemistry.
What is the conversion factor from grams per liter (g/l) to moles per liter (mol/l)?
The conversion factor from grams per liter (g/l) to moles per liter (mol/l) is the molar mass of the substance in grams per mole.
How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
What quantity serves as the conversion factor between the mass of a sample and how many moles the sample contains?
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
Is molar mass the conversion factor in stoichiometry?
While molar mass is not a conversion factor itself in stoichiometry, it plays a crucial role in converting between grams and moles of a substance. Molar mass is used to convert the mass of a substance to moles, enabling the stoichiometry calculations that involve mole ratios in chemical reactions.
What conversion factor for sodium is used to change mass to moles is?
The conversion factor for sodium is its molar mass, which is ~22.99 g/mol. To convert mass to moles, you divide the given mass by the molar mass of sodium.
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
What is the difference between converting amounts in moles to mass and converting mass to amounts in moles?
There are only two reverse operations.
Why cant molar mass be used as a conversion factor?

What is the conversion factor from grams per liter (g/l) to moles per liter (mol/l)?
The conversion factor from grams per liter (g/l) to moles per liter (mol/l) is the molar mass of the substance in grams per mole.

To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
What is the conversion factor from grams per mole (g/mol) to moles per liter (mol/L)?
The conversion factor from grams per mole (g/mol) to moles per liter (mol/L) is the molar mass of the substance in grams divided by its density in grams per liter.
What conversion does the value of the conversion factor depend upon the formula of the substance?
The value of the conversion factor depends on the units used to express the quantity being converted. Different units require different conversion factors to relate them accurately. The conversion factor is determined by the relationship between the original unit and the desired unit in the formula for the specific substance.
Why do we need to convert mass to moles in stoichiometry problems?
Converting mass to moles in stoichiometry problems is necessary because chemical reactions are based on the number of molecules involved, not their weight. By converting mass to moles, we can accurately determine the amount of each substance involved in a reaction and calculate the correct ratios for the reaction to proceed.
Which mathematical relationship should you use to convert moles of a substance into grams?
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
