One definition of a mole is the sum of the average atomic weights (mass) of a compound. In this case
2 Copper + 1 Sulfur = (2 * 63.55) + (1 * 32.07) = 159.17 grams per mole.
So
22 g / 159.17 g/mole = 0.14 mole of Cu2S
To find the number of grams in 5.0x10^22 molecules of nitrogen monoxide (NO), you need to convert the number of molecules to moles and then from moles to grams. First, calculate the number of moles by dividing the number of molecules by Avogadro's number (6.022x10^23 molecules/mol). Then, use the molar mass of NO (30.01 g/mol) to convert moles to grams.
To convert molecules to grams, you need to use the molar mass of the compound. For N2I6, the molar mass is 539.59 g/mol. First, calculate the number of moles in 8.2 x 10^22 molecules by dividing the number of molecules by Avogadro's number. Then, multiply the number of moles by the molar mass to find the grams.
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.
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms
First find the moles of CO2 by dividing 22 grams by the molecular weight of CO2(44.01g/mol) 22.0gCO2 1mole/44.01g CO2 = .50 molesCO2

To calculate the grams of CO2 produced by burning 22 grams of C3H8, first determine the moles of C3H8 using its molar mass, then use the balanced chemical equation for the combustion of C3H8 to find the moles of CO2 produced, and finally convert moles of CO2 to grams using the molar mass of CO2.
2.3 grams P (1mole P/30.97 grams) = 0.07427 moles Phosphorous 0.07427 moles P * 6.022 X 10^23 = 4.5 X 10^22 atoms of P in 2.3 grams P 4.5 X 10^22/6.022 X10^23 = 0.07427 moles of atoms in 2.3 grams of phosphorous
22 moles AgF (126.9 grams/1 mole AgF) = 2791.8 grams of silver fluoride.
To find the number of grams in 5.0x10^22 molecules of nitrogen monoxide (NO), you need to convert the number of molecules to moles and then from moles to grams. First, calculate the number of moles by dividing the number of molecules by Avogadro's number (6.022x10^23 molecules/mol). Then, use the molar mass of NO (30.01 g/mol) to convert moles to grams.
the same amount would have to stay in grams, so if 14 grams of nitrogen is formed, then 8 grams of oxygen, add those two together and you get 22. and that's 22 of the 40 grams used, so 40 subtracted by 22 is 18. 18 grams of water would be formed.
To convert molecules to grams, you need to use the molar mass of the compound. For N2I6, the molar mass is 539.59 g/mol. First, calculate the number of moles in 8.2 x 10^22 molecules by dividing the number of molecules by Avogadro's number. Then, multiply the number of moles by the molar mass to find the grams.
If 12 grams of carbon were used to form the 22 grams of carbon dioxide, this implies that 12 grams of oxygen were consumed in the reaction. Since 20 grams of oxygen were initially available, only 8 grams of oxygen are left unused.
To find the number of moles of solute in the solution, first, calculate the amount of HCl in grams using the formula: moles = molarity x volume (in liters). Then, convert the grams of HCl to moles by dividing by the molar mass of HCl (36.46 g/mol).
