You wish to prepare 250.0250.0 mL of a 400.0400.0 ppm w/v Fe2+Fe2+ ( MW=55.845 g/molMW=55.845 g/mol ) solution. How many grams o

Answer:

You need 0.702g of ferrous ammonium sulfate hexahydrate to prepare the desired solution.

Explanation:

First, you want to prepare 250.0mL of a 400.0ppm of Fe²⁺ (That is mg/L, w/v):

0.250L * (400mg / L) = 100mg Fe²⁺ = 0.1g Fe²⁺

Molar mass of Fe is 55.845g. moles are:

0.1g Fe²⁺ * (1mol / 55.845g) =

<h3>1.79x10⁻³ moles Fe²⁺</h3>

The Fe²⁺ comes from ferrous ammonium sulfate hexahydrate, as 1 mole of this salt contains 1 mole of Fe²⁺, moles of the salt you need are:

1.79x10⁻³ moles Fe(NH₄)₂(SO₄)₂.6H₂O.

To convert these moles to grams you must use molar weight, MW, thus:

1.79x10⁻³ moles Fe(NH₄)₂(SO₄)₂.6H₂O * (392.14g / 1mol) =

<h3>You need 0.702g of ferrous ammonium sulfate hexahydrate to prepare the desired solution.</h3>

Stochiometry .How many grams of CO2 is produced when excess CS2 reacts with 4 mols of O2? CS2+O2-SO2 Please balance equation.
Travka [436]

Mass of CO₂ produced : 58.67 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

CS₂ + 3O₂  -------> CO₂ + 2SO₂

mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)

From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂  :

\tt \dfrac{1}{3}\times 4=\dfrac{4}{3}

mass  CO₂ (MW= 44 g/mol) :

\tt \dfrac{4}{3}\times 44=58.67~g
