The answer is 3,33 moles.
1 mol of Na contains 6.02 x 1023 atoms (avogadro constant). Amount of Na = (1.31x1024) / (6.02x1023) = 0.227mol
In one mole of CaCl2, there are 2 moles of chloride ions since there are 2 chloride ions for every 1 CaCl2 molecule. Therefore, there are 2 * 6.022 x 10^23 = 1.2044 x 10^24 chloride ions in one mole of CaCl2.
The answer is 0,199 moles.
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
The chemical formula for water is H2O; therefore each formula unit has three atoms. Avogadro's number is defined as the number of formula units per mole. Therefore, the answer to the stated question is 3 X 6.022 X 1023 = about 1.8066 X 1024 atoms. (If the value "3" is not considered exact, only one significant digit is justified; in that instance, the answer should be written. as 2 X 1024.
1 mole CaCl2 = 6.022 x 1023 formula units CaCl2 1.26 x 1024 formula units CaCl2 x 1mol CaCl2/6.022 x 1023 formula units CaCl2 = 2.09 moles CaCl2
A mole is 6.022 × 1023 so 2.41 × 1024 molecules CaCl2 ÷ 6.022 × 1023 = 4.00 moles CaCl2.
4.5 moles NaCl = 4.5000000000001 formula units NaCl *******************2nd Opinion************* 4.5 moles of NaCl would contain 4.5 x (6.02 x 1023) formula units. = 2.7 x 1024 formula units
9.54*1024
Sodium chloride is an ionic crystalline salt, and does not form molecules. One unit of sodium chloride is called a functional unit. It is the lowest whole number ratio of ions represented in an ionic compound. 1 mole = 6.022 x 1023 formula units of NaCl 3 moles NaCl x 6.022 x 1023 formula units/mole = 1.8 x 1024 formula units of NaCl
To find the number of iron atoms in 5.33 moles of FeCl3, you first need to determine the molar mass of FeCl3 (162.2 g/mol). Then you can calculate the number of moles of Fe in FeCl3 (1 mole FeCl3 contains 1 mole Fe, so there are 5.33 moles of Fe in 5.33 moles of FeCl3). Finally, you can convert moles of Fe to atoms using Avogadro's number (6.022 x 10^23 atoms/mol).
1 mol of Na contains 6.02 x 1023 atoms (avogadro constant). Amount of Na = (1.31x1024) / (6.02x1023) = 0.227mol
Vanadium does not have moles but rather formula units. The formula unit for vanadium is a single atom. Therefore, the number of formula units in any number of atoms is equal to the number of atoms divided by Avogadro's Number, in this instance 7.17 X 10-3 formula units.
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.
4,96 x 1024 molecules of glucose is equal to 8,236 moles.
The answer is 0,199 moles.
The equivalent is two moles.
