Answer: The sample that contains the greater number of molecules is water.
Explanation: To calculate the number of molecules, it is used the Avogadro's number ( particles/molecules). So, considering that the mass to water and carbon dioxide is 1g (it can be any other number), the relationship between moles and molar weight is:
To water: = 0.05 moles.
Therefore,
1 mol ---- molecules
0.05 moles ---- x
x = molecules of water.
To carbon dioxide: = 0.02 moles.
Therefore,
1 mol ---- molecules
0.02 moles ---- y
y = molecules of carbon dioxide.
