Answer

1.39 x 10^20 molecules of testosterone

Work Step by Step

C19H28O2 testosterone. For each molecule of testosterone, there are 28 H atoms as we see by the formula. Therefore, if we have 3.88 x 10^21 H atoms then we divide this number by 28 to find the molecules of testosterone. 3.88 x 10^21 / 28 = 1.39 x 10^20 molecules of testosterone
