Answer:
Step-by-step explanation:
To find the number of molecules of NaCl that would have the same mass as 5.5 x 10^24 atoms of xenon, we need to know the molar mass of both substances. The molar mass of NaCl is 58.44 g/mol and the molar mass of xenon is 131.29 g/mol.
We can use the following formula to find the number of moles of xenon:
moles = mass/molar mass
We can use the number of moles of xenon to find the number of moles of NaCl.
As we know,
mass of 5.510^24 atoms of xenon = 5.510^24 atoms * 131.29 g/mol
mass of NaCl would be same as mass of xenon, so number of moles of NaCl would be same as number of moles of xenon.
moles of NaCl = moles of xenon = mass of xenon / molar mass of NaCl = (5.5*10^24 atoms * 131.29 g/mol) / 58.44 g/mol
So, the number of molecules of NaCl that would have the same mass as 5.5 x 10^24 atoms of xenon is (5.5*10^24 atoms * 131.29 g/mol) / 58.44 g/mol * Avogadro's number.
