What mass of iron is needed to react with sulfur in order to produce 96 grams of iron (iii) sulfide according to the following equation?

answer:

• Stoichiometry is a big word for a process that chemist’s use to calculate

amounts in reactions. It makes use of the coefficient ratio set up by balanced

reaction equations to make connections between the reactants and products

in reactions.

• Stoichiometry calculates the quantities of reactants and products in a

chemical reaction. The equation must be balanced!

• Questions that deal with amounts in reactions are examples of reaction

stoichiometry. We already have the tools necessary to solve this question.

We just need to learn a new way to apply skills such as writing chemical

formulas, calculating formula masses, and converting from mass to moles,

particles to moles, and volume of gases to moles.

• Mole to Mole Conversions- you must have the Mole Ratio.

Explanation:

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
