1 mol = 6.02 * 10^23 molecules
0.018 mol = 6.02 * 10^28 * 0.018 molecules
1.0836 * 10^27 molecules of CO2
The number of molecules in 0.75 moles of CO2 can be calculated using Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol. Thus, 0.75 moles of CO2 would contain about 4.5165 x 10^23 molecules.
The number of molecules is 0,90332112855.10e23.
1 mole CO2 = 6.022 x 1023 molecules 2.4mol CO2 x 6.022 x 1023 molecules CO2/1mol CO2 = 1.4 x 1024 molecules CO2
12×1023 molecules
We know for every 6.022 x 10^23 molecules, we have a mole of a substance, right? So if we have 3920molecules, we can use the above conversion factor to get: 3920 molecules CO2 x (1mol CO2/(6.022x10^23molecules CO2)) = 6.51 x 10^-21 moles CO2. There are three significant figures in this problem, from the 3929 molecules.
The notation (8.5 \times 10^{25}) refers to a quantity of molecules, not moles. To convert molecules to moles, divide by Avogadro's number, which is approximately (6.022 \times 10^{23}) molecules/mole. Thus, to find the number of moles in (8.5 \times 10^{25}) molecules of CO2, divide (8.5 \times 10^{25}) by (6.022 \times 10^{23}), resulting in approximately 141.5 moles of CO2.
Use Avagadro's Number (NA) ... 6.02 X 10^23 atoms (molecules) per mole. so ... 4830 / 6.02 X 10E23 = a really small number Molar equivalent, which my office calculator won't handle. Dude, if you're doing Chemistry homework, you should know this.
The number of molecules is 7,52767607125.10e23.
To find the number of moles in 2.408 x 10^24 molecules of CO2, you can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. Therefore, 2.408 x 10^24 molecules / 6.022 x 10^23 molecules per mole = about 4 moles of CO2.
molecular weight of carbon dioxide = 44u gram molecular weight of carbon dioxide = 44g given mass = 11g no. of moles = given mass divided by molar mass = 11 divided by 44 = 0.25moles.
To find the number of molecules in 33.6g of CO2, you first need to convert grams to moles. The molar mass of CO2 is 44 g/mol. Therefore, 33.6g is equal to 33.6g / 44 g/mol = 0.764 moles of CO2. Using Avogadro's number (6.022 x 10^23 molecules/mol), you can calculate that 0.764 moles of CO2 is equal to 0.764 mol x 6.022 x 10^23 molecules/mol = 4.6 x 10^23 molecules of CO2.
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
