A student used 6.34 x 10-3 kg of t-butanol in the synthesis of BHT. Assuming no other substances are limiting, how many grams of BHT can be formed? 9.42 g BHT 6.11 g BHT 18.8 g BHT 12.9 g BHT

The mass of BHT that can be formed is 18.8 grams

Explanation:

To calculate the number of moles, we use the equation:

    .....(1)

Given mass of t-butanol =      (Conversion factor: 1 kg = 1000 g)

Molar mass of t-butanol = 74 g/mol

Putting values in equation 1, we get:

The chemical equation for the formation of BHT from t-butanol follows:

By Stoichiometry of the reaction:

1 mole of t-butanol produces 1 mole of BHT

So, 0.086 moles of t-butanol will produce = 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:

Hence, the mass of BHT that can be formed is 18.8 grams
