In a certain problem you are asked to convert from the known mass of one compound into the mass of another compound. Place the required pieces of information into the most logical sequence that would result in proper calculations by helping reduce errors in order of operations. (4 points)

Question

Mole ratio from the balanced equation of moles of unknown to moles of known, Mass given from the problem of the known substance, Molar mass of unknown substance, Inverted molar mass of known substance.

Answer 1

To convert from the mass of one compound to the mass of another using stoichiometry, you can follow these steps in a logical sequence to ensure proper calculations and minimize errors in the order of operations:

1. Mass given from the problem of the known substance - Start with the mass of the known compound that you have.

2. Inverted molar mass of known substance - Convert the mass of the known substance to moles by using its molar mass. You'll use the inverted value (1/molar mass) to find moles.

3. Mole ratio from the balanced equation of moles of unknown to moles of known - Use the mole ratio from the balanced chemical equation to relate the moles of the known substance to the moles of the unknown substance.

4. Molar mass of unknown substance - Finally, convert the moles of the unknown substance to mass by using its molar mass.

This sequence ensures that you properly convert between mass and moles and use the stoichiometric relationships effectively.
