22. You are conducting an experiment in the chemistry lab where you are tasked with identifying the sample that contains a specific number of atoms. As part of the experiment, you are given several samples of different substances, and you need to determine which sample contains exactly 9.0times 10^23atoms Which sample below contains a total of 9.0times 10^23 atoms? 1.5 moles of Cu 0.75 moles of H_(2)O 0.50 moles of HCI 1.5 moles of H_(2)

To determine which sample contains exactly atoms, we need to calculate the total number of atoms in each given sample.1. **0.75 moles of :** Each molecule of water ( ) contains 3 atoms (2 hydrogen and 1 oxygen). Therefore, the total number of atoms in 0.75 moles of is calculated as follows: 2. **0.50 moles of HCl:** Each molecule of HCl contains 2 atoms (1 hydrogen and 1 chlorine). Therefore, the total number of atoms in 0.50 moles of HCl is calculated as follows: 3. **1.5 moles of :** Each molecule of contains 2 atoms (both hydrogen). Therefore, the total number of atoms in 1.5 moles of is calculated as follows: Comparing these calculations with atoms, none of the samples contain exactly atoms. However, if you are looking for the closest match, the sample of 0.50 moles of HCl contains atoms, which is less than , but it is the closest among the options provided.
