Make a model of n-butane (C4H10), and use wedges and dashed lines to represent bonds coming forward and going back respectively to draw the model of n-butane.
A scientist was able to isolate a few miligrams of pure testosterone, a primary sex hormone in males. When the scientist burned 5.00 mg of the testosterone sample he had isolated in oxygen, he found that 14.496 mg of CO2 and 4.373 mg of H2O were generated in the chemical reaction. Determine the molecular formula of testosterone if the molecular weight analysis showed that the molecular weight of testosterone is 288 g/mol.
Compound A is a compound found in goat's milk. A careful analysis showed that compound A contains 42.11% carbon and 6.48% hydrogen. No nitrogen or halogen was found. Determine the molecular formula of compound A if molecular weight analysis showed that compound A has a molecular weight of about 342 g/mol.
Give a molecular formula that corresponds to each of the following structures.
