How many hydrogen atoms are in 4.00 mol of ammonium sulfide?
(NH4)2Sthere are 8 hydrogen atoms for every molecule ofammoniumsulfideNA = 4 mol x 6.02 x 10^23 = 2.4 x 10^24 molecules of ammonium sulfidenumber of hydrogen atoms = 8 x2.4 x 10^24 = 2.93 x 10^25 ( 3 sig. figure)
How many hydrogen atoms are in 7.40 mol of ammonium sulfide?
The formula unit, which is the usual meaning of "mol" for an ionic compound such as ammonium nitride, is (NH4)2S. This shows that there are 2 X 4 or 8 hydrogen atoms in each formula unit. Avogadro's Number, which is about 6.022 X 1023, is the number of atomic formula units per mole. Therefore, the number of hydrogen atoms in 7.40 mol of ammonium sulfide is (8)(7.40)(6.022 X 1023) or 3.57 X 1025, to the justifiable number of significant digits. (The integer 8 is exact.)
How many atoms are in 62 moles of silver?
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
How many atoms of hydrogen are found in 5.29 mol of heptane C7H16?
There are 5.29 mol of heptane C7H16. In each molecule of heptane, there are 16 atoms of hydrogen. To find the total number of atoms of hydrogen, multiply the number of moles by Avogadro's number (6.022 x 10^23) and by the number of hydrogen atoms in each molecule of heptane (16). So, 5.29 mol x 6.022 x 10^23 x 16 = 5.10 x 10^25 atoms of hydrogen.
How many atoms are in 25 moles of fluorine?
Approx 7.925*10^23 atoms.
How many atoms are in 254.33 mol of O?
There are about 1.53 x 10^25 atoms in 254.33 mol of oxygen. This can be calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles.
How many Cu atoms are present in 85mol?
To calculate the number of Cu atoms in 85 mol, you need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. So, for 85 mol of Cu, the number of Cu atoms would be 85 mol x 6.022 x 10^23 atoms/mol = 5.12 x 10^25 Cu atoms.
How many atoms are in the 1.25x10 mol of mercury within the bulb of a thermometer?
To find the number of atoms in 1.25x10^4 mol of mercury, you need to use Avogadro's number, which is 6.022x10^23 atoms/mol. Multiply the number of moles by Avogadro's number: 1.25x10^4 mol * 6.022x10^23 atoms/mol = 7.5275x10^27 atoms in 1.25x10^4 mol of mercury.
How many atoms of H are in 2 mol of c8h18?
To determine the number of hydrogen atoms in 2 mol of C8H18, we first need to calculate the molar mass of C8H18. Carbon has a molar mass of approximately 12 g/mol, and hydrogen has a molar mass of approximately 1 g/mol. Therefore, the molar mass of C8H18 is (812) + (181) = 114 g/mol. Next, we use Avogadro's number (6.022 x 10^23) to calculate the number of molecules in 2 mol of C8H18, which is 2 mol * 6.022 x 10^23 molecules/mol. Since there are 18 hydrogen atoms in each molecule of C8H18, the total number of hydrogen atoms in 2 mol of C8H18 is 2 mol * 6.022 x 10^23 molecules/mol * 18 atoms/molecule = 2.17 x 10^25 hydrogen atoms.
What is 25 mmol converted to mol?
25 mmol equates to 0.025 mol
How many hydrogen atoms are in 8.70 mol of ammonium sulfide?
To determine the number of hydrogen atoms in 8.70 mol of ammonium sulfide (NH4)2S, first find the molar ratio of hydrogen atoms to formula units of ammonium sulfide. There are 8 hydrogen atoms in 1 formula unit of ammonium sulfide. Multiply this ratio by the number of formula units in 8.70 mol of ammonium sulfide to find the total number of hydrogen atoms. This calculation gives you the number of hydrogen atoms in 8.70 mol of ammonium sulfide.
How many moles are in 25 grams of UF6?
To calculate the number of moles in 25 grams of UF6, first determine the molar mass of UF6 (uranium hexafluoride) by adding the atomic mass of uranium (238.03 g/mol) to six times the atomic mass of fluorine (19.00 g/mol). This gives a molar mass of 238.03 + (6 * 19.00) = 352.03 g/mol. Next, divide the given mass of 25 grams by the molar mass to find the number of moles: 25 g / 352.03 g/mol ≈ 0.071 moles. Therefore, there are approximately 0.071 moles in 25 grams of UF6.
How many hydrogen atoms are in 593 grams of water?
