Answer:
number of moles of the compound 53 mole
Explanation:
Given that:
The total energy liberated = - 2870 kJ ( here , the negative sign typical implies the release of energy due to the combustion reaction)
The equation of the reaction can be represented as:
The energy needed to synthesize 1 mole of compound X = - 54.1 kJ.mol
Thus;
The total energy = numbers of moles of compound × Energy needed to synthesize 1 mole of compound X
Making the numbers of moles of the compound the subject; we have;
numbers of moles of compound =
number of moles of the compound = 53.04990 mole
number of moles of the compound 53 mole to two significant figure
<u>Answer: </u>
<u>For 1:</u> The volume of HCl required is 6 L.
<u>For 2:</u> The volume of HCl required is 9 L.
<u>For 3:</u> The volume of sulfuric acid required is 4.5 L.
<u>Explanation:</u>
To calculate the volume of acid, we use the equation given by neutralization reaction:
......(1)
where,
are the n-factor, molarity and volume of acid
are the n-factor, molarity and volume of base
- <u>For 1:</u>
We are given:
Putting values in equation 1, we get:
Hence, the volume of HCl required is 6 L.
- <u>For 2:</u>
We are given:
Putting values in equation 1, we get:
Hence, the volume of HCl required is 9 L.
- <u>For 3:</u>
To calculate the volume of acid, we use the equation:
where,
are the normality and volume of acid
are the normality and volume of base
We are given:
Putting values in above equation, we get:
Hence, the volume of sulfuric acid required is 4.5 L.
