by weighing out the bit of insulin that you want to find how much of it there is
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
The total number of molecules is equal.
To find the number of oxygen molecules in the balloon, you can first calculate the number of moles of O2 using its molar mass (32 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the balloon contains approximately 1.15 x 10^23 oxygen molecules.

The number of water molecules it contains.
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
There are approximately 2.65 × 10^26 bromine molecules in the flask. This is calculated by multiplying Avogadro's number (6.022 × 10^23 molecules/mol) by the number of moles of bromine present in the flask (440 mol).
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.

By knowing the no of moles in a gas. Because , in any gas one mole of gas occupies Avagadro number of molecules.
The total number of molecules is equal.

Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the balloon contains approximately 1.15 x 10^23 oxygen molecules.
The gas that contains the most molecules in a 5.0 L sample would be the one with the highest molar mass. This is because the number of molecules in a gas sample is directly proportional to its molar mass.
By the definition of Avogadro's Number, each mole contains 6.022 X 1023 molecules. Therefore, (9.25 X 1024)/(6.022 X 1023) or 15.4 moles are required, to the justified number of significant digits.
Any substance that contains Avogadro's number of particles is called a mole. A mole is a unit in chemistry that represents 6.022 x 10^23 particles, which is the number of atoms or molecules in 1 mole of a substance.
