the Atomic Mass of FeS2 is 110. You cannot find the no. of moles in a mole of FeS2 coz it is only a mole.
If the hydrate contains 45% water, then one mole of the hydrate will contain 0.45 moles of water.
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
The molar mass of helium is approximately 4.00 g/mol. Therefore, for 2.00 moles of helium, the total mass contained would be 2.00 moles x 4.00 g/mol = 8.00 grams.
1 mole Zn3(PO4)2 (2 moles P/1 mole Zn3(PO4)2) 2 moles phosphorous ===============
In water (H2O), there are 2 moles of hydrogen (H) atoms for every 1 mole of water. Therefore, in 2.95 moles of water, there are 2 * 2.95 = 5.9 moles of hydrogen atoms.
the Atomic Mass of FeS2 is 110. You cannot find the no. of moles in a mole of FeS2 coz it is only a mole.
There are 4.53 x 10^24 manganese atoms in 7.5 moles of manganese.
If the hydrate contains 45% water, then one mole of the hydrate will contain 0.45 moles of water.
Since ammonia has a chemical formula of NH3, it contains one mole of nitrogen and three moles of hydrogen per mole of ammonia. Therefore, 3 moles of ammonia contain 3 moles of nitrogen and 9 moles of hydrogen atoms.
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
1 mole
There are 5 moles of sulfur in 5 moles of H2SO4, as there is 1 mole of sulfur in each mole of H2SO4.
There are 3.5 moles of carbon in 3.5 moles of calcium carbonate. This is because there is only one mole of carbon in each mole of calcium carbonate, as the formula for calcium carbonate is CaCO3.
The molar mass of helium is approximately 4.00 g/mol. Therefore, for 2.00 moles of helium, the total mass contained would be 2.00 moles x 4.00 g/mol = 8.00 grams.
There is 1 mole present in 1 lb-mole.
1 mole Zn3(PO4)2 (2 moles P/1 mole Zn3(PO4)2) 2 moles phosphorous ===============
One mole of Ba(NO3)2 contains one mole of barium (Ba), two moles of nitrate ions (NO3-), and six moles of oxygen atoms (3 oxygen atoms per nitrate ion).
