How many hydrogen atoms are present in 1.0 g of NH₃?

Question

Quizplus · Accepted Answer

To determine the number of hydrogen atoms present in the given compound, we need to first calculate the number of moles of the compound and then use Avogadro's number to convert to the number of hydrogen atoms. The molecular weight of the compound NH₃ can be calculated as follows: N + H + S + (B*13) = 14.01 + 1.008 + 32.06 + (10.81*13) = 234.96 g/mol Now, we can use this to calculate the number of moles of the compound: 1.0 g / 234.96 g/mol = 0.00426 mol Finally, we can use Avogadro's number (6.022 x 10^23) to convert the number of moles to the number of hydrogen atoms: 0.00426 mol * 1 hydrogen atom / (1 molecule) * 6.022 x 10^23 molecules/mol = 1.1 x 10^23 hydrogen atoms Therefore, the answer is D) 1.1 x 10^23 atoms.
