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 (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
There are 6.022x10^23 molecules in 1.00 mol of anything.
There are 3.505 x 10^23 molecules of H2O in 0.583 mol of H2O, because 1 mol of any substance contains 6.022 x 10^23 molecules.
There are 1.08 x 10^24 sulfur dioxide molecules in 1.80 mol of sulfur dioxide.
The number of bromine molecules present in the flask can be calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol. In this case, there are 0.380 mol of bromine, so the number of bromine molecules present is 0.380 mol x 6.022 x 10^23 molecules/mol.
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
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.
The answer is 12,046.1023 molecules.
There are 6.022x10^23 molecules in 1.00 mol of anything.
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.
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
There are approximately 5.8 x 10^24 molecules in 9.6 mol of C2H4. This is calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol.
divide this number by avagadros number to get moles. (5.16x1024)/(6.02x1023)=8.57mol of H2O as there are 3 atoms in each molecule there are 3x8.57=25.7 moles of atoms.
The number of molecules is 7,2265690284.10e23.
5.95378*1023
There are approximately 2.41 x 10^23 molecules in 0.400 mol of N2O5. This is calculated by multiplying Avogadro's number (6.022 x 10^23 mol^-1) by the number of moles given.
There are 3.505 x 10^23 molecules of H2O in 0.583 mol of H2O, because 1 mol of any substance contains 6.022 x 10^23 molecules.
