The answer is 19 ahhahaha
no the best source is blood.
<span>The average molar bond enthalpy of the carbon-hydrogen bond in a CH4 molecule is 416 KJ/mol.
(+716.7 + (4 x 218) - (- 74.6) ) / 4
= + 1663.3 / 4
= 416</span>
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.
