Given that 10.00mL of 0.1894M CH3COOH was titrated with 0.2006M NaOH in this experiment, calculate the volume, in mL, of NaOH re

sertanlavr [38]

Answer:

$V_{base}=9.442mL$

Explanation:

Hello!

In this case, when acetic acid is titrated with sodium hydroxide, the following chemical reaction is carried out:

$CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O$

Whereas there is a 1:1 mole ratio between the acid and the base, which means that at the equivalence point we evidence:

$n_{acid}=n_{base}$

Which in terms of volumes and concentrations is written as:

$M_{acid}V_{acid}=M_{base}V_{base}$

Thus, solving for the required volume of base, we obtain:

$V_{base}=\frac{M_{acid}V_{acid}}{M_{base}}=\frac{0.1894M*10.00mL}{0.2006M}\\\\ V_{base}=9.442mL$

Best regards!

How many moles of iron (Fe) will be produced from 6.20 moles of carbon monoxide (CO) reacting with excess iron (III) oxide (Fe2O

bonufazy [111]

Answer:

4.13 moles of Fe

Explanation:

Step 1: Write the balanced equation

3 CO + Fe₂O₃ ⇒ 2 Fe + 3 CO₂

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CO to Fe is 3:2.

Step 3: Calculate the moles of Fe formed from 6.20 moles of CO

We will use the previously established molar ratio.

6.20 mol CO × 2 mol Fe/3 mol CO = 4.13 mol Fe
