How many grams of water (H_2O) have the same number of oxygen atoms as 1.0 (mol} of oxygen gas?
make senses
It would take 2.0 moles of H2O to have the same number of O atoms as 1 mole of O2.
2 moles of H2O have a mass of 2 x 18 g.
Do you mean "makes sense" ?
I hope so.
"It makes sense." I was in a rush when I typed that.
To determine the number of grams of water that have the same number of oxygen atoms as 1.0 mole of oxygen gas, we need to use the molar mass and Avogadro's number.
1. The molar mass of water (H2O) is calculated by adding the molar masses of hydrogen (H) and oxygen (O). Hydrogen has a molar mass of approximately 1.01 g/mol, and oxygen has a molar mass of approximately 16.00 g/mol. Therefore, the molar mass of water (H2O) is approximately 18.02 g/mol.
2. Avogadro's number is defined as 6.022 x 10^23 molecules per mole. This means that one mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, or ions).
3. Now, we need to determine the number of oxygen atoms present in 1.0 mole of oxygen gas. Oxygen gas (O2) is made up of two oxygen atoms (O). So, for every mole of oxygen gas, there are 2 moles of oxygen atoms.
4. Using Avogadro's number, we can determine the number of oxygen atoms in 1.0 mole of oxygen gas by multiplying the number of moles of oxygen atoms by Avogadro's number. Therefore, 2 moles of oxygen atoms x (6.022 x 10^23 atoms/mole) = 1.2044 x 10^24 oxygen atoms.
5. Since water (H2O) has one oxygen atom (O) per molecule, we know that 1.2044 x 10^24 oxygen atoms correspond to the same number of water molecules.
6. Finally, we can calculate the mass of these water molecules by multiplying the molar mass of water (18.02 g/mol) by the number of moles. Therefore, 1.2044 x 10^24 molecules x (18.02 g/mol) = approximately 2.17 x 10^25 grams of water.
Therefore, approximately 2.17 x 10^25 grams of water (H2O) have the same number of oxygen atoms as 1.0 mole of oxygen gas.
