Question

A sample of the male sex hormone testosterone, C19H28O2, contains 3.38×1021 atoms of hydrogen.

A. How many atoms of carbon does it contain?

B. How many molecules of testosterone does it contain?

Answer 1

The molecular formula of male sex hormone .. Testosterone's Ciq H28022 Now, each molecule of testosterone ma contains 19 Carbon atoms, 28 hydrogen atoms and 2 Oxygen atoms. Now, according to Avogadro's hypothesis, Imole testosterone contain: > 6:023x102Prolecular I oftestosterone Since Imdecule contains 228 hydrogen atoms, ... Imole testosterone contains a 28X6.023x1023 Perembem of H But according to the given problem, n atomis. the testosters one sample contains. > 3.38x102! atoms of heydorogeru CH). :28x6.023x183 hydrogen atoms have > Imole sample ^: 3.38x1021 üc213.38X1021 28X6-023X1023" = 2.004810. a mole

A. Amole of testosterone Sample contains : 61023X1023molecules of testosterone, each testosterone molecule of have 19 Carbon atoms, - Imole sample contains a 1986:023X1023 carbonatoms, - 20004 X20-4 mole is = 19*6:023X102-3 x 2.004x109cc 2 2.293 x 1021 Carbon atomes 18. Imole of sample containws 6•023X1023 testosterone O molecules. - 20004x10-46 ( 26.023x1023x2.004x10-4 . molecules 21.207x1020 molecule of testostersone.
