Assuming the Water is pure, 10g of water contains approximately 3. 33*10^23 water molecules (via conversion to moles of water, and multiplying it by Avagadro's number), multiply this by another 3 (since every water molecule contains 3 atoms, 2 hydrogen and 1 oxygen), leaving us with 10^24 atoms in total. Keeping this in view, how many atoms are there in 65. So one mole of water contains 6. 022×10^23 number of water molecules. We know that every water molecule is made up of two hydrogens and one oxygen which means that every water molecule contains 3 atoms. So, to get number of atoms in 18g of water, we will multiply Avogadro's number by 3. Thus, there are 3. 35 * 10^22 molecules of water in 1 gram. Now, each molecule of water has 2 hydrogen atoms and 1 oxygen atom. This means that there are 3 atoms in each molecule. Likewise, people ask, how many atoms of hydrogen are there in 10. Each molecule of water contains 2 H: then total H-atoms in 10 grams of water = 3. 34 E 23 x 2 = 6. 64 E 23 atoms. 18 gram water means 1 mole H2O. There are 2 hydrogen atoms and 1 oxygen atom in H2O.

A mass in grams numerically equal to the molecular weight contains one mole of molecules, which is known to be 6. 02 x 10^23 (Avogadro's number). So if you have x grams of a substance, and the molecular weight is y, then the number of moles n = x/y and the number of molecules = n multiplied by Avogadro's number.

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

Avogadro's number is a very important relationship to remember: 1 mole = 6. 022×1023 6. 022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

Helium has the most number of mol out of all the options and will thus have the highest number of atoms.

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6. 02 x 10^23.

One sulfuric (H2SO4) molecule has 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms. You can also say one mole of sulfuric acid has two mols of hydrogen atoms, 1 mol of sulfur atoms, and 4 moles of oxygen atoms. So in total, we have 7 mols of atoms. But that's in 1 mol of sulfuric acid.

It is equal to Avogadro's number (NA), namely 6. 022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

https://www.quora.com/Is-the-amount-of-cl-atoms-contained-in-a-mole-of-cl2-Avogadros-number-6-022*10

No. The amount of Cl atoms contained in a mole of Cl2 will be 2*( 6. 022 e23)=1. 204 e24. The reason for this is that one molecule of Cl2 will have 2 atoms of Cl, joined together by a bond.
