very very very few ;)
There are millions of different kinds of molecules, more organic ones than inorganic because they are tailored to a biological role. An estimate of the total number of molecules making up the earth is difficult to estimate, and changes slightly all the time. The number of atoms, however, can be extrapolated from the mass and composition of the Earth. It is about 1.33 x 1050 atoms. The number of molecules should then be within the next two lower orders of magnitude, or at least 1 x 1048.
Scientists estimate that chemical evolution, the process by which complex molecules formed from simpler ones, took place over billions of years on early Earth. This gradual process led to the development of more complex molecules, eventually paving the way for life to emerge.
The act of respiration involves a chemical reaction taking in Oxygen from the outside and carbon from the animal producing CO2. Since there was a change of material, these C02 molecules are new, and therefore not the same as what came in. Also, it might be argued that any substance taken into the lungs that exits as the same was not part of the breath (such as water from a drowning victim is not "breathing water" after being revived with CPR). And while these CO2 molecules might be taken in by other organisms that do not process them, plants are credited with the conversion back to O2. So regardless of the gas you're taking in, you can never breathe the same gas that Einstein did, because he already "breathed it all up."
The viscosity of a gaseous mixture can be calculated using the Chapman-Enskog equation, which takes into account the molecular weights, sizes, and collision cross-sections of the gas molecules in the mixture. The viscosity is typically expressed in terms of the collision diameter and the Lennard-Jones potential parameters of the gas molecules. Various empirical correlations and models may also be used to estimate the viscosity of gaseous mixtures under different conditions.
A detailed summary of project objectives and outcomes is not typically a required element of preparing a proposal estimate. The estimate usually focuses on the costs associated with completing the project, such as labor, materials, and overhead expenses.
It is tough to tell the exact estimate.
It has changed drastically throughout the years so an estimate is impossible.
The number of atoms in the universe is estimated at 1078 to 1082. So the number of molecules would be smaller than this, obviously. Reference: http://www.universetoday.com/36302/atoms-in-the-universe/
The act of blinking requires a very small amount of energy, which can be provided by only a few molecules of ATP. Studies estimate that a blink may require around 1-2 molecules of ATP to execute the movement of the muscles involved.
The latest estimate of the total number of net ATP molecules that can be maximally generated by the complete aerobic respiration of glucose is approximately 30-32 ATP molecules. This value can vary slightly depending on the specific conditions and efficiency of the process.

It is difficult to provide an exact number, but a rough estimate is on the order of Avogadro's number, which is approximately 6.022 x 10^23 molecules. This can vary depending on the molecular weight and structure of the starch.
The towns and cities in this novel are fictional, although you could roughly estimate Adam's journey throughout Massachusetts and Vermont.
Because answer will definitely fall within the range but not necessarily group together evenly throughout the whole range.
A typical cup of tea (about 240 milliliters) contains approximately 10^24 molecules. This estimate includes water molecules as the main component, as well as dissolved compounds from the tea leaves, such as caffeine and tannins. Given that water is the primary ingredient, the number of molecules can vary slightly depending on the tea concentration and type. However, the sheer scale of molecules involved in even a small volume highlights the complexity of tea at the molecular level.
42 ok so this person put only 42 molicules in the universe? wrong! there are so many molecules in the universe that not even sientists could figure that out but my guess is that there are billions and zilions of molicules in the universe.
Too difficult to even try to estimate as pies are of many different sizes, pies are mixtures that vary practically infinitely in possible ingredients that can come in widely varying amounts, the molecules in pies vary from small ones (e.g. water) to gigantic polymer molecules (e.g. starches, celluloses, proteins, DNA, RNA), etc. Perhaps if you reworded your question to identify a specific size and type of pie someone might be able to give you an estimate that might be within a couple of orders of magnitude of the actual number.
