Final answer:
To solve a mass-to-mass stoichiometry problem, three conversion steps are typically needed: converting the given mass to moles using molar mass, using the stoichiometric factor from the balanced equation to find moles of the second substance, and then converting those moles back to mass.
Step-by-step explanation:
The number of conversion factors/steps needed to solve a mass-to-mass stoichiometry problem typically involves three main steps:
- Convert the known mass of the first substance to moles using the substance's molar mass as the conversion factor.
- Use the balanced chemical equation to find the stoichiometric factor, which allows conversion of the moles of the first substance to moles of the second substance.
- Convert the moles of the second substance to its corresponding mass, again utilizing its molar mass as the conversion factor.
These steps highlight the process of converting from the mass of one substance involved in a chemical reaction to the mass of another substance using stoichiometry calculations.
