Explain why a 5.0 gram sample of water does not have the same number of particles as 5.0 grams of sugar?

Question

thank you!

Answer 1

Key concepts involved in this problem:

1 mole of a substance contains 6.022 x 1023 particles.

6.022 x 10^23 prticles mol -1= Avogadro's Number.

N = n x Avogadro's Number
N = number of particles in the substance
n = amount of substance in moles (mol)

 

So the real question is... Is 5.0 g of water the same number of moles as 5.0 g of sugar?  The answer is no.  There are 18.01 g of water in 1 mole of water which is not the same for sugar.  You will need to calculate the number of moles of sugar in 5 g. sugar.  Use your periodic table.  I am assuming C6H12O6?
