Answer: 5.44 x 10^24
Step-by-step explanation:
Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number:
1-To go from moles to molecules, multiply the number of moles
by 6.022 x 10^23.
2-To go from molecules to moles, divide the numbers of molecules
by 6.022 x 10^23.
Given number of moles (9.04) We can compensate directly using the formula (Moles equal number of atoms/molecules over Avogadro's number)
Number of molecules = 9.04 x 6.022 x 10^23= 54.43888 x 10^23
now applying significant figure rules the answer is rounded to 3 digits and wrote in scientific notation making the final answer 5.44 x 10^24
