Final answer:
Trisilylamine, with the corrected formula (SiH3)3N, has 9 hydrogen atoms in each molecule.
Step-by-step explanation:
The chemical formula for trisilylamine is not accurately given in the question, but based on the name 'trisilylamine,' we can deduce that it contains a single nitrogen atom bonded to three silyl groups (SiH3). If we correct the chemical formula provided to be (SiH3)3N, we can then calculate the number of hydrogen atoms. Each silyl group contains 3 hydrogen atoms, and there are 3 silyl groups, so we have a total of 3 x 3 = 9 hydrogen atoms plus the hydrogen atoms that may be directly attached to the nitrogen, if any. In this case, no hydrogen atoms are directly attached to nitrogen in trisilylamine, so the total number of hydrogen atoms in each molecule of trisilylamine is 9.
