To convert the number of atoms to moles:
You need the number of atoms in a substance which is usually given. Ex. 1.65 × 1024 atoms of Magnesium. Then the formula is as follows:
# of atoms ÷ (Avogrado's Constant) = # moles
1.65 × 1024 atoms ÷ (6.02 × 1023) = 2.74 moles of Mg
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
To find the number of molecules of LiCl in a 127.17 g sample, you first need to convert the mass of LiCl to moles using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules. Calculate the number of molecules of LiCl in the sample using these values.
To convert molecules to moles, you use Avogadro's number which is 6.022 x 10^23 molecules/mol. Divide the number of molecules (4830) by Avogadro's number to find the moles of CO2. In this case, 4830 molecules CO2 is equal to 8.01 x 10^-21 moles CO2.
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.
To determine the number of bromine molecules, you need to first convert the mass of liquid bromine to moles using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
to convert molecules into moles, simply use the formula n=N/NA where NA is Avogadro's number(6.022E23). This formula can be rearranged so to convert from moles to molecules (N=nNA). to convert from molecules to moles you use the equation n=N/NA where NA is Avogadro's number (6.022E23)
Multiply the number of moles by the molecular weight.
To convert from moles to molecules, you use Avogadro's number, which is approximately 6.022 x 10^23 molecules/mole. You multiply the number of moles by Avogadro's number to get the number of molecules.
To convert from molecules to moles, you need to divide the number of molecules by Avogadro's number (6.022 x 10^23). This will give you the number of moles of the substance.
The answer is 88 moles.
To convert from number of molecules to moles, we use Avogadro's number: 1 mole = 6.022x10^23 molecules. Therefore, 1.0x10^19 HCl molecules is equal to 1.66x10^-5 moles of HCl.
To convert molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23). Therefore, 3.4 x 10^23 molecules of H2SO4 is equal to approximately 0.056 moles.
To convert from molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). Therefore, 98.3 molecules of aluminum hydroxide would be approximately 0.163 moles.
To calculate the number of molecules, first convert 450 g of water to moles (8 moles). With a 1.3 m solution, there are 1.3 moles of sucrose for every 1 liter of water. So, you will need 10.4 moles of sucrose for 8 moles of water. Finally, use Avogadro's number to convert moles to molecules, giving you approximately 6.23 x 10^23 molecules of sucrose.
To convert from molecules to moles, you need to divide the number of molecules by Avogadro's number, which is 6.022 x 10^23. In this case, 7.95E22 molecules of NH3 would be approximately 0.132 moles.
To find the number of molecules of CH3Cl in 101 grams of the substance, you would first convert 101 grams of CH3Cl to moles using its molar mass. Once you have the moles of CH3Cl, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
To find the number of molecules in 565 grams of ZnCrO4, you first need to convert grams to moles using the molar mass of ZnCrO4. Then, use Avogadro's number (6.022 x 10^23 molecules/mole) to convert moles to molecules.
