What gives air its weight?
Air has weight because it is made up of molecules that have mass. The weight of the air is due to the gravitational force pulling down on these molecules. The more air molecules present in a given volume, the greater the weight of the air.
Why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food?
The total weight of a food item includes not only the weight of the nutrient molecules but also water, fiber, and other non-nutrient components. Nutrient molecules like carbohydrates, proteins, and fats only make up a portion of the total weight because they are typically smaller molecules that are densely packed with energy. This is why the grams of nutrient molecules in a food may not add up to the total weight of the food item.
Why does air pressure becomes lower as water molecules are added to the air?
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
What gives gas molecules there weight?
molecules have weight because of its density and mass(amount of material) of a molecule. in other words how much stuff (neutrons, electrons, and protons) is in an atom.
How do you convert molecules to gram?
You first divide the amount of molecules by avagadros number (6.022x10^23) to find out how many moles you have. Then you find out the molecular weight of the compound. You multiply the number of moles by the molecular weight to give you your weight in grams.
How many molecules of THC does 26μg represent?
To determine the number of molecules in 26μg of THC, we need to know the molecular weight of THC to convert the mass to moles. Then, we can use Avogadro's number (6.022 x 10^23) to find the number of molecules. Without the molecular weight of THC, we cannot determine the exact number of molecules.
How many molecules in a mass of 3.9mg of C27H46O?
The molecular weight of it is 386.654g/mol. Convert mass to grams (i.e. 0.0039g). divide mass by molec weight to get 1.0083573x10^-5 moles. Multiply this by avagadros number to get the amount of molecules. this gives you 6.072x10^18 molecules.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
What is the weight in grams of 3.36 1023 molecules of copper sulfate (CuSO4)?
What is the weight in grams of 3.36 × 1023 molecules of copper sulfate (CuSO4)?
What are micromolecules?
Micromolecules are small molecules that typically have a molecular weight of less than 900 daltons. They include compounds like amino acids, sugars, and small lipids. Micromolecules play important roles in various biological processes such as metabolism and signaling.
Why do animals use lipids instead of carbohydrates as energy storing molecules?
As they store a lot more energy, weight for weight.
What is the weight of air on earth is called?
The weight of air on Earth is called atmospheric pressure. It is the force exerted by the weight of air molecules in the Earth's atmosphere on a surface.
