How can you calculate no of moles from no of atoms?
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.
How many moles are in 5.00x1026 molecules of fluorine?
To find the number of moles in 5.00x10²⁶ molecules of fluorine, you can use Avogadro's number, which is approximately 6.022x10²³ molecules per mole. Dividing the number of molecules by Avogadro's number gives: [ \text{Moles} = \frac{5.00 \times 10^{26} \text{ molecules}}{6.022 \times 10^{23} \text{ molecules/mole}} \approx 83.1 \text{ moles} ] Thus, there are approximately 83.1 moles of fluorine in 5.00x10²⁶ molecules.
How many mol of potassium are represented by 7.85e23 potassium atoms?
To find the number of moles of potassium, we need to first determine the molar quantity of potassium atoms in one mole. A mole is equivalent to Avogadro's number, which is 6.022e23 atoms per mole. So, 7.85e23 potassium atoms would be approximately 1.304 moles of potassium.
What is the mass in grams of 1.501023 atoms Mg?
This can be found using one of the most important constants for chemistry: Avogadro's number. According to wikipedia, the standard atomic weight of magnesium is 24.3050 grams per mole. Using Avogadro's number, we know there's 6.0221415 × 1023 atoms per mole, so if you divide the standard atomic weight of magnesium by Avogadro's number, you can get number of grams per atom of magnesium (i.e. the mass of a single magnesium atom in grams). (24.3050 g/mole) / (6.0221415 x 1023 atoms/mole) = 4.03564 g/atom
What are two forms of the conversion factor that will convert one mole to number of objects and number of objects to one mole?
One mole is equivalent to 6.022x10^23 atoms. Which is also known as Avagadro's number. For example if you have 46 gms of sodium. The number of sodium atoms is 2x6.022x10^23. This is because we have two moles of sodium. (Molar mass of sodium is 23 grams per mole.)
How can you calculate no of moles from no of atoms?
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
How do you calculate molecules to moles?
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
How do I convert 76.0 grams of C4H10 to liters?
First, find out what the temperature and pressure of the gas is. Next, determine the mass per mole - this one I'll give you, it's 58.12 grams per mole. Divide 76 by 58.12 to get the number of moles of gas you have. Then, use the ideal gas law to determine the number of liters of gas per mole at the temp and pressure your gas is. Finally, multiply the liters per mole by the number of moles you have, and you've got it.
How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
Convert moles per liter into micro moles per liter?
1 mole = 106 micromoles
How many moles are represented by 4.70 x 1026 atoms of uranium?
To determine the number of moles, first calculate the number of moles in one mole of uranium using Avogadro's number (6.022 x 10^23 atoms/mol). Then, divide the given number of atoms by the number of atoms per mole to find that 4.70 x 10^26 atoms of uranium represents 7.81 moles.
How many moles are in 2.408 x 1024 molecules of CO2?
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.
How many moles of bromide are there in Iron Bromide?
To determine how many moles of bromide are in iron (III) bromide (FeBr3), you can use the chemical formula FeBr3 to see that there are three moles of bromide ions for every mole of iron (III) bromide. So, the number of moles of bromide ions is equal to the number of moles of FeBr3.
How do you calculate the number of molecules in moles?
You can calculate the number of molecules in a mole using Avogadro's number, which is 6.022 x 10^23. Simply multiply the number of moles by Avogadro's number to get the number of molecules. This calculation allows you to convert between moles and molecules.
How is the number of moles of an element determined from known mass?
The molar mass is the measurement of mass per one mole of a substance. If the mass of a matter is known, divide it from the molar mass to obtain the number of moles.
