1 mole ------------ 6.02x10²³ molecules
? moles ----------- 1.505x10²³ molecules

(1.505x10²³) x 1 /  ( 6.02  x10²³ ) =

(1.505x10²³) / ( 6.02x10²³ ) =

= 0.25 mol

Answer A

hope this helps!

Answer: Option (a) is correct.

Explanation:

Molecules of sugar given = \(1.505 \times 10^{23}\)

According to Avogadro's number it is known that 1 mole contains \(6.023 \times 10^{23}\).

Therefore, calculate the moles of sugar present in the sample as follows.

   Number of moles =  \(\frac {1.505 \times 10^{23}}{6.023 \times 10^{23}}\)

           = 0.25 mol

Thus, the moles of sugar present in the sample is 0.25 mol.
