What conversion factor is used when converting moles to mass?
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.
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 molar mass's role in reaction-stoichiometry?
Stoichiometry is based on the fact that chemical reactions occur in ratios of moles of all substances. The problem is that there is no device that directly measures moles. We do have a device to measure mass, so molar mass is used in stoichiometric calculations to give results which are measurable.
Molar Mass Of Magnesium from gas law stoichiometry where would this apply?
The molar mass of magnesium can be determined using gas law stoichiometry when the mass of magnesium reacted and the volume of gas produced are known. By measuring the volume of gas produced during the reaction of magnesium with an acid, and knowing the pressure, temperature, and number of moles of gas, the molar mass of magnesium can be calculated using the ideal gas law equation PV = nRT and stoichiometry relationships.
Why are different masses of each element required to react with the same amount of hydrogen?
Each element has a different molar mass and Molarity, using stoichiometry the conversion of molar mass can explain why.

What is the molar mass of a substance in amu converted to kg/mol?
To convert the molar mass of a substance from atomic mass units (amu) to kilograms per mole (kg/mol), you need to multiply the molar mass in amu by the conversion factor 1.66054 x 10-27 kg/amu. This will give you the molar mass in kg/mol.
What is the molar mass of the compound in grams per mole (g/mol) converted to daltons (da)?
To convert the molar mass of a compound from grams per mole (g/mol) to daltons (da), you need to multiply the molar mass by the conversion factor 1 g/mol 1 dalton. This means that the molar mass in grams per mole is the same as the molar mass in daltons.
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).
Why do you need to convert mass to moles in stoichiometry problems?
Converting mass to moles in stoichiometry problems is necessary to determine the amount of reactants or products involved in a chemical reaction. This conversion allows you to compare the amounts of different substances based on their molar quantities rather than their masses, making it easier to balance equations and calculate the quantities of reactants needed or products produced.
How do you convert PO4-P to P2O5?
To convert PO4-P to P2O5, you can use the molar mass of each compound. Phosphorus (P) has a molar mass of 30.97 g/mol, while P2O5 has a molar mass of 141.94 g/mol. So, you can calculate the conversion factor by dividing the molar mass of P2O5 by the molar mass of P to determine how much P2O5 is equivalent to 1 unit of PO4-P.
What is the molar mass of a substance in dalton units converted to grams per mole (g/mol)?
The molar mass of a substance in dalton units can be converted to grams per mole (g/mol) by multiplying the dalton value by 1.66054 x 10-24. This conversion factor allows you to express the molar mass in grams per mole.
