You should edit the dopamine molecule by tampering with its polar groups. Polar groups affect chemical's physical properties including hydrophobicity.
The empirical formula is obtained by calculating the mole ratios of the atoms in the elements.
The number of moles =mass/ R.A.M
For hydrogen, no. of moles=8/1=8
For oxygen, no. Of moles=64/16=4
The tabular solution is attached.
Answer:
The percent yield of carbon disulfide is 78.8%
Explanation:
Percent yield of reaction = (Produced yield / Theoretical yield) . 100
5C + 2SO₂ --> CS₂ + 4CO
In the reaction 5 moles of C, produce 1 mol of CS₂
40 g / 12 g/m = 3.33 moles
Then, this is the rule of three:
5 mol of C produce 1 mol of CS₂
3.33 moles of C, will produce ( 3.33 .1)/5 = 0.666 moles
Mol . molar mass = mass → 0.666 mol . 76.12 g/m =50.7 g (Theoretical yield)
(40 g / 50.7 g) . 100 = 78.8%
