A cohesive force is best described as the attraction between two liquid molecules. Cohesive forces are the inter-molecular forces between similar molecules, which cause a tendency in liquids to resist separation. For example a water drop is composed of water molecules that like to stick together
The values of N, log N and ln N are all worked out below.
We have the number N as 8.99
hence;
1) lnN = ln(8.99) = 2.196
log N = log (8.99) = 0.954
2) If we have ln N as 3.949
N = e^3.949 = 51.88
So;
log N = log (51.88) = 1.715
3) log N = 0.134
N = Antilog (0.134 ) = 1.36
ln N = ln (1.36) = 0.307

Mass of water is 11.52 grams.
Overall chemical equation for reaction of combustion a compound containing only carbon and hydrogen:
CxHy + O₂ → xCO₂ + y/2H₂O
m(CxHy) = 7.02 g; mass of the compound
m(O₂) = 25.5 g; mass of oxygen
m(CO₂) = 21.0 g; mass of carbon dioxide
m(H₂O) = ?; mass of water
Conservation of matter states that the mass of the reactants have to be equal to the mass of the products.
m(CxHy) + m(O₂) = m(CO₂) + m(H₂O)
7.02 g + 25.5 g = 21.0 g + m(H₂O)
m(H₂O) = 32.52 g - 21.0 g
m(H₂O) = 11.52 g; mass of water

The equation is balanced because the molecules on reactants side is equivalent to the amount of molecules on the product side.
6CO2 (g) + 6H2O (l) ----> C6H12O6 (aq) + 6O2 (g)
