n=m/M so, the atomic number for Phosphorus is 30.973... we divide the atomic number by the amount of grams we have so n= 2.3/ 30.973= 0.07425822490556
= 0.14 mol.
3,42 moles of phosphorus trichloride have 469,6686 g.
4,70 moles of tetraphosphorus decaoxide contain 582,56 g phosphorus.
8,75 moles of oxygen are needed.
Molar mass of P2O5 is 142gmol-1. You need 17.2 moles of p.
1 mole Zn3(PO4)2 (2 moles P/1 mole Zn3(PO4)2) 2 moles phosphorous ===============
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
There are 2.21 x 10^24 atoms of phosphorus in 3.65 moles of phosphorus triiodide.
3,42 moles of phosphorus trichloride have 469,6686 g.
The number of moles of phosphorus depends on the given quantity or mass of phosphorus. To calculate the number of moles, you need to know the molar mass of phosphorus (about 30.97 g/mol) and the mass of the sample. You can then use the formula moles = mass/molar mass to find the number of moles.
4,70 moles of tetraphosphorus decaoxide contain 582,56 g phosphorus.
To convert atoms to moles, you divide by Avogadro's number, which is approximately 6.022 x 10^23. Therefore, 1.20x10^25 atoms of phosphorus is equal to 20 moles of phosphorus.
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
8,75 moles of oxygen are needed.
Quite a few! 392 grams phosphorous (1 mole P/30.97 grams) = 12.7 moles phosphorous ===================
23grams
To find the number of moles of phosphorus atoms in 100 grams of P4S10, we first need to determine the molar mass of P4S10 which is 284.26 g/mol. Next, we calculate the number of moles of P4S10 in 100 grams by dividing 100 g by the molar mass to get 0.352 moles of P4S10. Since there are 4 phosphorus atoms in each P4S10 molecule, there are 0.352 moles x 4 = 1.41 moles of phosphorus atoms in 100 grams of P4S10.
There are 1 atom of phosphorus in each formula unit of Ba3(PO3)2. One formula unit of Ba3(PO3)2 contains 2 moles of phosphorus. Therefore, in 5.26 moles of Ba3(PO3)2, there are 5.26 x 2 = 10.52 moles of phosphorus, which is equivalent to 10.52 x 6.022 x 10^23 atoms.
