Answer :
Sure, let's calculate the number of moles of citric acid based on the given information. Here's the step-by-step solution:
1. Identify the given data:
- The molecular weight of citric acid is 192.124 grams/mole.
- The mass of citric acid (in grams) used from the previous question (let's denote this as [tex]\( m \)[/tex] grams).
2. Apply the formula for calculating moles:
[tex]\[ \text{Number of moles} = \frac{\text{mass of citric acid}}{\text{molecular weight of citric acid}} \][/tex]
3. Substitute the values into the formula:
- Let [tex]\( m \)[/tex] be the mass of citric acid in grams.
- Molecular weight of citric acid = 192.124 grams/mole.
[tex]\[ \text{Number of moles of citric acid} = \frac{m \, \text{grams}}{192.124 \, \text{grams/mole}} \][/tex]
4. Simplify the expression:
This formula can be simplified to express the number of moles directly. However, since the mass of citric acid [tex]\( m \)[/tex] is not provided in the problem, the final number of moles will depend on this [tex]\( m \)[/tex] value.
So, if you can provide the specific mass of citric acid in grams (denoted as [tex]\( m \)[/tex]), you can simply substitute [tex]\( m \)[/tex] into the formula to find the number of moles.
For example, if the mass of citric acid used is 384.248 grams:
[tex]\[ \text{Number of moles of citric acid} = \frac{384.248 \, \text{grams}}{192.124 \, \text{grams/mole}} = 2 \, \text{moles} \][/tex]
Thus, to calculate the precise number of moles, you would need the exact mass of citric acid in grams from the previous question.
