How many moles of sodium are equal to 6.32 x 1025 atoms?
Quite a few. 6.32 X 10^25 atoms sodium (1 mole Na/6.022 X 10^23) = 105 moles of sodium
How many molecules are there in 18.9 moles of chlorine gas?
One mole is 6.022 × 1023 (or 602,200,000,000,000,000,000,000) bits of anything. You have 18.9 moles. Thus: 18.9 × (6.022 × 1023) = 1.138158 × 1025 (or 11,381,580,000,000,000,000,000,000) molecules Cl2.
How many atoms does 0.5 kg sodium contain?
First calculate the moles of sodium moles = 500 g/ 23 = 21.739 ... Remember the Avogadro Number. 6.022 x 10^(23) is the number of atoms in one mole Hence , multiplying 6.022 x 10^(23) X 21.739... = 1.309 x 10^(25) atoms in 0.5 kg of sodium .
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
How many moles of pottassium are represented by 6.85x1025 potassium atoms?
To find the number of moles, you first need to recognize that 6.022 x 10^23 atoms make up one mole (Avogadro's number). Thus, divide 6.85 x 10^25 atoms by Avogadro's number to get the number of moles. Therefore, the number of moles of potassium in this case would be 11.4 moles.
How many molecules of carbon dioxide gas are there in 34 moles?
There are approx 2.05*1025 molecules.
How many moles of He are 1.20 x 1025 atoms He?
In order to find how many Moles of He are 1.20 x 1025 atoms of He, you need to divide 1.20 x 1025 atoms by the Avagadro's number (6.022 x 1023) The answer is 19.9 moles of He.
How many moles of sodium are equal to 6.32 x 1025 atoms?

How many moles of Mg are in 1.48 x 1025 Mg atoms?
The element magnesium does not form polyatomic molecules with specific numbers of atoms. Therefore, one mole ofmagnesium contains Avogadro's Number of atoms, and Avogadro's number is about 6.022 X 1023. Therefore, 1.48 X 1025 atoms contains (1.48/6.022) X10(25-23) or about 24.7 moles, to the justified number of significant digits.
How many molecules are in 7.4 g H'S?
By definition, Avogadro's Number is the number of molecules or formula units in the number of grams corresponding to the gram molecular weight or gram formula unit, and by experiment, Avogadro's Number is about 6.022 X 1023. Therefore, 7.75 X 1025 formula units contains (7.75 X 1025/6.022 X 1023) or 1.29 X 102 moles or formula units, to the justified number of significant digits.
