There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
To calculate the number of molecules in 16.75 grams of H2O, we first need to convert grams to moles (using the molar mass of H2O), and then convert moles to molecules using Avogadro's number. The molar mass of H2O is 18.015 g/mol. After converting, there are approximately 3.52 x 10^23 molecules in 16.75 grams of H2O.
A mole of any substance is 6.02214179×1023 (just use 6.022) molecules of it. So 1.23 moles of any substance (including water) is 1.23 x 6.022 x 1023 molecules, whatever that is...
There are 6.022x10^23 molecules in 1.00 mol of anything.
C2H4 + H2O --> C2H5OHReaction balanced at 1:1:1 mole of each compound, so you'll need 0.132 mol C2H4 and this is equal to:0.132 (mol C2H4) * 28 (g/mol C2H4) = 3.696 g C2H4 = 3.70 g C2H4
1 mole H2O = 6.022 x 1023 molecules 0.357mol H2O x 6.022 x 1023 molecules/mol = 2.15 x 1023 molecules H2O
To calculate the number of molecules in 2.81g of H2O, you first need to convert grams 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: 2.81g H2O / 18.015 g/mol = 0.156 moles H2O; 0.156 moles H2O x 6.022 x 10^23 molecules/mol = 9.40 x 10^22 molecules of 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.
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
The answer is 2,3 moles water.
To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
To determine the number of molecules in 6.9 g of water (H2O), you first need to convert grams to moles. The molar mass of water is approximately 18 g/mol. Therefore, 6.9 g is equal to 6.9/18 = 0.383 moles of water. Next, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in 0.383 moles of water, which is approximately 2.3 x 10^23 molecules.
In 1 molecule of H2O, there are 2 atoms of H. Therefore, in 1 mol of H2O, there are 2 mol of H. So, in 4.51 mol of H2O, there would be 4.51 * 2 = 9.02 mol of H.
The number of molecules is 15,055 352 142 5.10e23.
Formula mass / Formula weight / Molecular mass / Molecular weight of H2O = (1*2) + 16 = 18g 1 mol of H2O = 18g H2O 1 mol of H2O = 6.023 * 10^23 molecules In 18g H2O there are 6.023 * 10^23 molecules. So, In 1g H2O there are (6.023 * 10^23) / 18 molecules = 3.346 * 10^22 molecules Therefore, In 7.3g H2O there are (3.346 * 10^22) * 7.3 molecules = 2.443 * 10^23 molecules Ans: 2.443 * 10^23 molecules
Each mole of a substance contains 6.022 E23 molecules or atoms of that substance. Four moles of H2O will contain 2.4088 E24 molecules.
