To convert 0.77 x 10^24 molecules (of any compound) to moles, we use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.
Step 1: Determine the conversion factor
1 mole = 6.022 x 10^23 molecules
Step 2: Set up the conversion
0.77 x 10^24 molecules * (1 mole / 6.022 x 10^23 molecules)
Step 3: Calculate the result
0.77 x 10^24 / 6.022 x 10^23 = 1.28 moles
Step 4: Determine the correct significant figures
The original number, 0.77 x 10^24, has two significant figures, so the final answer should also have two significant figures. Therefore, the result is approximately 1.3 moles (rounded to two significant figures) of the compound.
