How many hydrogen atoms are in 8.30 moles of ammonium sulfide?
8.30 moles (NH4)2S (8 moles H/1 mole (NH4)2S)(6.022 X 1023/1 mole H) = 3.99 X 1025 atoms of hydrogen ========================
How many moles are equal to 3.6 x10 to the 23 power molecules of oxygen gas O2?
One mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes.So you multiply 23 with 6.02 × 1023 to get 1.38 × 1025
How many atoms of hydrogen are found in 5.29 mol of heptane C7H16?
1,36 moles C5H12 (12 moles H/1 mole C5H12)(6.022 X 10^23/1 mole H) = 9.83 X 10^24 atoms of hydrogen
How many moles of tungsten atoms are in 4.8x10 25 atoms of tungsten?
The answer is B, 8.0 x 10^1 There are 6.023 x 10^23 atoms in one mole, of any substance. So simply divide 4.8 x 10^25 by 6.023 x 10^23, to get about 79.69 which if you convert into scientific notation, is about 8.0 x 10^1 the answer for me was A but that's on novanet
How many hydrogen atoms are in 3.40 mol ammonium sulfide?
1.64 x 1025
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 ibuprofen contain 7.4x1025 atoms of Carbon?
C13H18O2 = ibuprofen 7.4 X 1025 carbon atoms (1 mole C atoms/6.022 X 1023)(1 mole ibuprofen/13 mole carbon) = 9.5 moles ibuprofen ------------------------------
How many moles are in 5.0 x 1025 atoms of iron?
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
How many moles of pottassium are represented by 6.85x1025 potassium atoms?
A mole of potassium consists of Avogadro's number of atoms. Therefore 6.85 X 1025 atoms comprises (6.85 X 1025)/(6.022 X 1023) or 114 moles, to the justified number of significant digits.
How many atoms does 0.5 kg sodium contain?
1.30*1025
How many atoms are there in 100.0 moles of Si?
100 times Avogadro's Number = 6.022 X 1025.
How many moles in 25 g of carbon?
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
How many hydrogen atoms are in 8.30 moles of ammonium sulfide?
8.30 moles (NH4)2S (8 moles H/1 mole (NH4)2S)(6.022 X 1023/1 mole H) = 3.99 X 1025 atoms of hydrogen ========================
How many hydrogen atoms are there in 7.30 moles of ethanol?
7.30 C2H6O (6 moles H/1 mole C2H6O)(6.022 X 1023/1 mole H) = 2.64 X 1025 atoms of hydrogen =====================
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 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 moles of He are 1.20 x 1025 atoms?
The element helium does not technically have "moles", because its atomsdo not form any chemical bond with other helium atoms. Its formula unit is a single atom. Avogadro's Number, the number of formula units in a gram atomic mass, is about 6.022 X 1023. Therefore, 1.20 x 1025 atoms constitutes (1.20 X 1025)/(6.022 X 1023) or about 19.9 formula masses, to the justified number of significant digits.
