How many moles are 1.20 x 10^25 atoms of phosphorus? 2. How many atoms are in 0.750 moles of zinc? 3. How many molecules are in 0.400 moles or N2O5?<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n Let’s address each question one by one, including the necessary calculations and explanations:<\/p>\n\n\n\n To calculate the number of moles from the number of atoms, we use Avogadro’s number, which is approximately (6.022 \\times 10^{23}) atoms per mole. The formula for this calculation is:<\/p>\n\n\n\n [ For phosphorus:<\/p>\n\n\n\n [ So, there are approximately 19.94 moles<\/strong> of phosphorus in (1.20 \\times 10^{25}) atoms.<\/p>\n\n\n\n To find the number of atoms in a given number of moles, we again use Avogadro\u2019s number:<\/p>\n\n\n\n [ For zinc:<\/p>\n\n\n\n [ So, there are approximately (4.52 \\times 10^{23})<\/strong> atoms in 0.750 moles of zinc.<\/p>\n\n\n\n To find the number of molecules in a given number of moles of a compound, we use the same approach as with atoms:<\/p>\n\n\n\n [ For (N_2O_5):<\/p>\n\n\n\n [ So, there are approximately (2.41 \\times 10^{23})<\/strong> molecules in 0.400 moles of (N_2O_5).<\/p>\n\n\n\n Let me know if you need any further clarification or if you’d like me to generate a diagram for these calculations!<\/p>\n","protected":false},"excerpt":{"rendered":" How many moles are 1.20 x 10^25 atoms of phosphorus? 2.
