Question

A sample of sugar (C12H22O11) contains

1.505 × 1023 molecules of sugar. How many moles of sugar are present in the sample? Answer without doing any calculations.

Answer 1

Answer: 0.25 mol

Step-by-step explanation:

Use the formula n=N/NA

n= number of mols

N = number of particles

Nᵃ = Avogadros constant = 6.02 x

So, n=

The 10 to the power of 23 cancels out and you are left with 1.505/6.02, which is approximately 1/4. This is the same as 0.25 mol.

Hope this helped :)
