Answer: The mass of BHT that can be formed is 18.8 grams
Explanation:
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] .....(1)
Given mass of t-butanol = [tex]6.34\times 10^{-3}kg=6.34g[/tex] (Conversion factor: 1 kg = 1000 g)
Molar mass of t-butanol = 74 g/mol
Putting values in equation 1, we get:
[tex]\text{Moles of t-butanol}=\frac{6.34g}{74g/mol}=0.086mol[/tex]
The chemical equation for the formation of BHT from t-butanol follows:
[tex]\text{t-butanol + p-cresol}\rightarrow \text{BHT}[/tex]
By Stoichiometry of the reaction:
1 mole of t-butanol produces 1 mole of BHT
So, 0.086 moles of t-butanol will produce = [tex]\frac{1}{1}\times 0.086=0.086mol[/tex] of BHT
Now, calculating the mass of BHT from equation 1, we get:
Molar mass of BHT = 220 g/mol
Moles of BHT = 0.086 moles
Putting values in equation 1, we get:
[tex]0.086mol=\frac{\text{Mass of BHT}}{220g/mol}\\\\\text{Mass of BHT}=(0.086mol\times 220g/mol)=18.8g[/tex]
Hence, the mass of BHT that can be formed is 18.8 grams
