Suppose a solution was too concentrated for an accurate reading with the spectrophotometer. The concentrated solution was dilute

yan [13]

Using the law of <span>dilution:

</span>initial Molarity = 3.5x10⁻⁶ M

<span>Initial volume = 4.00 mL
</span>
final Molarity = ??

final volume = 1.00 mL

Therefore:

Mi x Vi = Mf x Vf

(3.5x10⁻⁶) x 4.00 = Mf x 1.00

1.4x10⁻⁵ = Mf x 1.00

Mf = 1.4x10⁻⁵ / 1.00 =

1.4x10⁻⁵ M

Cloud [144]

Answer: Assuming the question: 3.54 ml (3 sig figs)

Explanation:

I don't see a question, but will assume it is "What volume is needed to obtain 26.5 grams?

If so:

(26.5 g)/(7.48 ml) = 3.54 ml (3 sig figs)

4Fe +302–> 2Fe2O3 how many moles of Fe2O3 are produced when 0.27 moles of Fe is reacted?

Svet_ta [14]

Answer:

0.14 moles of Fe₂O₃

Explanation:

Given parameters:

Number of moles of Fe = 0.27moles

Unknown:

Number of moles of Fe₂O₃ = ?

Solution:

To solve this problem, we are going to the work from the known specie to the unknown using their number of moles.

We first obtain the balanced equation of the reaction;

4Fe + 3O₂ → 2Fe₂O₃

The equation above is balanced;

4 moles of Fe produced 2 moles of Fe₂O₃

0.27 moles of Fe will produce $\frac{0.27 x 2}{4}$ = 0.14 moles of Fe₂O₃
