A mole of water is about 18 grams or 18 milliliters of water.A mole of water has 6.022 x 10^23 water molecules. And 10.0 grams of has 3.345 × 10^23 water molecules. And there are 3 total atoms in water molecules, which is H2O.
(3.34 × 10^23)*3=1.006 × 10^24
Which means that 1x10^24 atoms are in 10.0 grams of water.

The number of molecules in 10 grams of a substance depends on the molecular weight of the substance. You can calculate the number of molecules by first converting the mass to moles using the molecular weight and then using Avogadro's number (6.022 x 10^23) to determine the number of molecules.

∙ 14y agoIt all depends on the molecules in question. If you're looking at H2, ten grams is five moles.
Now, at the OTHER end of the scale...any really heavily crosslinked polymer is one molecule. Some of them weigh many tons.

How many molecules are in 565 grams of ZnCrO4?
To find the number of molecules in 565 grams of ZnCrO4, you first need to convert grams to moles using the molar mass of ZnCrO4. Then, use Avogadro's number (6.022 x 10^23 molecules/mole) to convert moles to molecules.
How many grams are in 8.2 x 10 to the 22 molecules of N2I6?
To convert molecules to grams, you need to use the molar mass of the compound. For N2I6, the molar mass is 539.59 g/mol. First, calculate the number of moles in 8.2 x 10^22 molecules by dividing the number of molecules by Avogadro's number. Then, multiply the number of moles by the molar mass to find the grams.
How many grams in 5.0x1022 molecules of nitrogen monoxide?
To find the number of grams in 5.0x10^22 molecules of nitrogen monoxide (NO), you need to convert the number of molecules to moles and then from moles to grams. First, calculate the number of moles by dividing the number of molecules by Avogadro's number (6.022x10^23 molecules/mol). Then, use the molar mass of NO (30.01 g/mol) to convert moles to grams.

How many molecules are in 654.5 grams calcium chloride?
To find the number of molecules in 654.5 grams of calcium chloride, you need to first convert the mass to moles using the molar mass of calcium chloride. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules.
How many molecules of carbon monoxide are present in 3.69 grams of this compound?
To find the number of molecules of carbon monoxide in 3.69 grams, first calculate the number of moles using the molar mass of carbon monoxide (28.01 g/mol). Next, use Avogadro's number to determine the number of molecules in those moles of carbon monoxide.
How many molecules are there in 95.2 g of water?
To find the number of molecules in 95.2 g of water, first calculate the number of moles using the molar mass of water (18.015 g/mol). Next, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. So, (95.2 , \text{g} \times \frac{1 , \text{mol}}{18.015 , \text{g}} \times 6.022 \times 10^{23} , \text{molecules/mol}) gives you the number of molecules.
How many molecules are there in 200 grams of h2o?
There are approximately 1.12 x 10^24 molecules in 200 grams of H2O. This calculation is based on the molar mass of water (18.01528 g/mol) and Avogadro's number (6.022 x 10^23 molecules/mol).
How many oxygen molecules O2 are in 2.56 grams of O2?
There are 0.08 moles of O2 in 2.56 grams of O2. Since each mole of O2 contains 6.022 x 10^23 molecules, there are approximately 4.82 x 10^22 oxygen molecules in 2.56 grams of O2.
How many molecules of carbon dioxide are there in 1.0 grams of the gas?
The gram molecular mass of carbon dioxide is about 44.01 grams. By definition, this value is the number of grams of carbon dioxide that contains Avogadro's Number ("AN") of molecules. Avogadro's Number is about 6.022 X 10^23. Therefore the number of molecules in 1 gram is (1/44.01)(AN) or 2 X 10^21 molecules, to the justified number of significant digits.
How many grams are in 4 molecules of water?
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, for 4 molecules of water, the total mass would be 4 x 18 = 72 grams.
