Isopentyl acetate (c7h14o2), the compound responsible for the scent of bananas, can be produced commercially. interestingly, bees release about 1μg (1 × 10-6 g) of this compound when they sting. the resulting scent attracts other bees to join the attack. (a)calculate the number of molecules of isopentyl acetate released in a typical bee sting. (b)calculate the number of carbon atoms present.

1 μg of C₇H₁₄O₂ contains 4.62 × 10¹⁵ molecules and there are 3.23 × 10¹⁶ atoms of carbon present.

First, we want to calculate the number of molecules in 1 μg (1 × 10⁻⁶ g) of C₇H₁₄O₂. We will use the following relationships.

The molar ratio of C₇H₁₄O₂ to C is 1:7. The number of atoms of C in 4.62 × 10¹⁵ molecules of C₇H₁₄O₂ is:

1 μg of C₇H₁₄O₂ contains 4.62 × 10¹⁵ molecules and there are 3.23 × 10¹⁶ atoms of carbon present.

The answer to your question is:

a) 4.64 x 10 ¹⁵ molecules

b) 9.28 x 10 ¹⁵ atoms of O2

Explanation:

MW C7H14O2 = 84 + 14 + 32 = 130 g

a)        130 g of C7H14O2 1 mol of C7H14O2

           1 x 10 ⁻⁶ g                    x

           x = 7.7 x 10 ⁻⁹ mol

          1 mol of C7H14O2     6 .023 x 10 ²³ molecules

          7.7 x 10⁻⁹ mol              x

          x = 4.64 x 10¹⁵ molecules

b)      130 g of C7H14O2     1 mol of C7H14O2

         1 x 10⁻⁶  C7H14O2       x

         x = 7.7 x 10 ⁻⁹ mol of C7H14O2

        1 mol of C7H14O2       2 mol of O2

        7.7 x 10 ⁻⁹                   x

         x = 1.54 x 10⁻⁸ mol of O2

       1 mol of O2  6.023 x 10 ²³ atoms

       1.54 x 10 ⁻⁸     x

        x = 9.28 x 10 ¹⁵ atoms of O2

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
