How can you get the molar mass of insulin knowing just the grams of insulin in a sample and the number of molecules that that sample contains?
To find the molar mass of insulin, you first need to calculate the number of moles of insulin in the sample using the Avogadro's number and the number of molecules. Then, divide the grams of insulin by the number of moles to find the molar mass. The molar mass is expressed in grams per mole.

How many H2O molecules are in a mole of water molecules?
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.
How many molecules of water are in 5.65 moles of water?
There are approximately 3.40 x 10^24 molecules of water in 5.65 moles of water. This can be calculated using Avogadro's number (6.022 x 10^23 molecules/mol) multiplied by the number of moles.
What if three identical flasks contain three different gases at stp flask a contains ch4 flask b contains CO2 flask c contains n2 which flask contains the largest number of molecules?
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.
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
A balloon contains 7.36 g of oxygen gas (O2). How many oxygen molecules are in the balloon?
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.
How many H2O molecules are in a mole of water molecules?
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.
What does the name of a hydrate indicate about its cpmosition?
The number of water molecules it contains.
How many moles of water are present in half mole of water?
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.
If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
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).
How many molecules of water are in 5.65 moles of water?
There are approximately 3.40 x 10^24 molecules of water in 5.65 moles of water. This can be calculated using Avogadro's number (6.022 x 10^23 molecules/mol) multiplied by the number of moles.

How can you get the number of particles of gas?
By knowing the no of moles in a gas. Because , in any gas one mole of gas occupies Avagadro number of molecules.
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.

Which gas contains the most molecules in a 5.0 l sample?
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.
How many moles of C3H8 contains 9.25 times 10 to the 24 power molecules of C3H8?
To find the number of moles in 9.25 x 10^24 molecules of C3H8, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). So, 9.25 x 10^24 molecules / 6.022 x 10^23 molecules/mol = approximately 15.4 moles of C3H8.
Any substance that contains Avogadro's number of particles is called a?
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.
