How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
The molar mass of water is 18 g/mol, so 29.2 g is equivalent to 1.62 mol of water. Through electrolysis, each water molecule decomposes into 1 molecule of oxygen and 2 molecules of hydrogen. Therefore, 1.62 mol of water will produce 1.62 mol of oxygen molecules, which is equivalent to 9.73 x 10^23 molecules of oxygen.
How many molecules of H2O are in 54.3 g H2O?
To find the number of molecules in 54.3 g of water (H2O), you first need to convert the mass of water to moles using the molar mass of water (18.015 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The calculation would be: 54.3 g / 18.015 g/mol = 3.013 moles, then, 3.013 moles * 6.022 x 10^23 molecules/mol = 1.816 x 10^24 molecules of H2O in 54.3 g of water.
How many water molecules are in a block of ice containing 0.500mol of water H 2 O?
There are approximately 3.01 x 10^23 water molecules in a block of ice containing 0.500 mol of water (H2O) because 1 mol of water contains 6.022 x 10^23 molecules.
How many molecules of water are there in 12g of ice?
[10.0(g) / 18.0(g/mol H2O)] * 6.02.10+23(molecules/mol) = 3.34.10+23 molecules in 10 g of H2O(never mind the physical state: solid, liquid, vapor; it's all 10.0 grams of it)
How many molecules are in 6.30 mol CO2?
There are 3.80 x 10^24 molecules of CO2 in 6.30 mol. This can be calculated by using Avogadro's number, which is 6.022 x 10^23 molecules/mol.
How many water molecules are in a block of ice containing 1.50 mol of water (H2O)?

How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
How many molecules of water are there in 1.802 grams of water?
To calculate the number of water molecules in 1.802 grams, first find the molar mass of water (H2O = 18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles (1.802 g / 18.015 g/mol = 0.1 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of water molecules (0.1 mol * 6.022 x 10^23 molecules/mol = 6.022 x 10^22 molecules).
How many Molecules are contained in 0.900 mol O2?
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
The molar mass of water is 18 g/mol, so 29.2 g is equivalent to 1.62 mol of water. Through electrolysis, each water molecule decomposes into 1 molecule of oxygen and 2 molecules of hydrogen. Therefore, 1.62 mol of water will produce 1.62 mol of oxygen molecules, which is equivalent to 9.73 x 10^23 molecules of oxygen.
How many many water molecules are in a drop of water?
The reactants of water H (2) + O (2) exist as diatomic molecules only. Therefore, 1 mol of Hydrogen + 1 mol of Oxygen will give 2H(2)O (or 2 mols of Water). Water always exists as a diatomic molecule as well, and this is why it will always have 2 molecules as the most basic possible ratio.
How many molecules are in 2 mol of tryptophan?
The answer is 12,046.1023 molecules.
How many molecules of H2O are in 54.3 g H2O?
To find the number of molecules in 54.3 g of water (H2O), you first need to convert the mass of water to moles using the molar mass of water (18.015 g/mol).

How many water molecules are in a block of ice containing 0.500mol of water H 2 O?
There are approximately 3.01 x 10^23 water molecules in a block of ice containing 0.500 mol of water (H2O) because 1 mol of water contains 6.022 x 10^23 molecules.
How many molecules are present in 17.0 moll of water?
To find this out you simply times 17 by avogadros number 17mol H2O X 6.022x10^23 molecules of anything/mol of anything mols cancel and you are left in molecules of H2O the answer is 1.024x10^25 molecules H2O
How many molecules of water are there in 12g of ice?
[10.0(g) / 18.0(g/mol H2O)] * 6.02.10+23(molecules/mol) = 3.34.10+23 molecules in 10 g of H2O(never mind the physical state: solid, liquid, vapor; it's all 10.0 grams of it)
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.
