Question

4. How many moles are in 9.12 x 1023 molecules of sugar? And I want the steps to so that I can understand better

Answer 1

Answer:

Step 1: List the known quantities and plan the problem.

Known

number of C atoms = 4.72 × 10 24

1 mole = 6.02 × 10 23 atoms

Unknown

4.72 × 10 24 = ? mol C

One conversion factor will allow us to convert from the number of C atoms to moles of C atoms.

Step 2: Calculate.

 

4.72 times 10^{24} text{atoms C} times frac{1  text{mol C}}{6.02 times 10^{23} text{atoms C}}=7.84  text{mol C}

Step 3: Think about your result.

The given number of carbon atoms was greater than Avogadro’s number, so the number of moles of C atoms is greater than 1 mole.  Since Avogadro’s number is a measured quantity with three significant figures, the result of the calculation is rounded to three significant figures.
