Answer:
190.4g
Explanation:
1.6mol of KBr (119.002g KBr/1 mol) = 190.4g
since you want to find grams, take the molar mass of KBr (119.002) per 1 mol and use it as your conversion factor (119.002g KBr/1 mol) which will then cancel out mols and leave you with grams.
Answer:
359 grams FeO
Explanation:
To find how many grams FeO are produced, you need to use the moles of Fe, convert it to moles of FeO (using the mole-to-mole ratio from the equation), then convert the moles of FeO to grams (using the molar mass from the periodic table).
2 Fe + O₂ --> 2 FeO
Molar Mass (FeO) = 55.845 g/mol + 16.00 g/mol
Molar Mass (FeO) = 71.845 g/mol
5.00 moles Fe 2 moles FeO 71.845 grams
---------------------- x ------------------------ x ---------------------- = 359 grams FeO
2 moles Fe 1 mole FeO
