3,42 moles of phosphorus trichloride have 469,6686 g.
4,70 moles of tetraphosphorus decaoxide contain 582,56 g phosphorus.
1) Get the chemical formula to determine the number of each type of atom present in the compound. 2) Multiply the atomic weight (get it from the periodic table) of each element by the number of atoms of that element present your specific compound 3) Do the Sum in unit grams/mole NaCl (1x23 grams/mole Na) + (1x 35.5 grams/mole Cl) = 58.5 grams/mole NaCl
Aluminum carbonate is Al2(CO3)3. If you have 7.0x1022 particles of it, then that's 7.0x1022/6.02x1023 = 0.116 moles. The compound has a molar mass of 234g/mol, so 234x0.116=27.144 grams.
There is said to be about 600 grams of nitrogen in 1.00 pound of ammonium and 130 pounds of phosphorus available in 1.00 pounds of ammonium phosphate.
92.4 grams
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
The molcular weight of PCl3 is 30.97 + (35.45 X 3) = 137.32 The amount of P required to make 5.49 g (30.97 / 137.42) X 5.49 = 1.23g
4,70 moles of tetraphosphorus decaoxide contain 582,56 g phosphorus.
The daily requirement of phosphorus is 800. How many grams of phosphorus are needed?
Dinitrogen tetraoxide, or N2O4 has a molar mass of 92.011 grams per mole. This means there are 0.0435 moles present.
Quite a few! 392 grams phosphorous (1 mole P/30.97 grams) = 12.7 moles phosphorous ===================
