moles of p2o5

Or you could specify any number of moles. moles O2 = 144 g / 32 g/mol = 4.5 mol Learn vocabulary, terms, and more with flashcards, games, and other study tools. Share to Twitter Share to Facebook Share to Pinterest. Express your answer to three significant figures and include the appropriate units. A- What is the maximum number of moles of P2O5 that can theoretically be made from 112 g of P4 and excess oxygen? N(P2O5) = NA*n(P2O5), where n(P2O5) = m(P2O5)/M(P2O5) and NA is Avogadro constant and 6.022x1023 molecules/mol N(P2O5) = NA*m(P2O5)/M(P2O5) = 6.022x1023*0.27/142 = 1.145x1021 molecules So the total number of atoms is: N(Atoms) = 7* N(P2O5… How many moles of silver acetate are found in 3.44 x 1026 f. u. of silver acetate? molar mass of P2O5 = 142 g/mol Noe we will find the moles of 0.560 g P2O5: moles = mass / molar mass moles = 0.560 g / 142 g/mol moles = 0.0039 mol now we will find the atoms present in 0.0039 moles: 0.0039 * 6.02 * 10 Moles=given wt./molecular weight 1.25=given wt./70 given wt.=70*1.25=87.5 gm For this you need the atomic mass of Ca. Two moles of acetic acid (Ethanoic acid) are heated with P2O5 , product formed is acetic anhydride .P2O5 act as dehydrating agent . You will also need From your mass of MgNH4PO4.6H2O collected, calculate your value a) for the mass of "P2O5" in the initial mass of fertilizer analyzed b) the % "P2O5" in the fertilizer. p2o5 reaction, For the reaction H2(g) + 1/2 O2 -- H2O delta H = - 286 KJ/mol , calculate the enthalpy change when 2.80 g of water is produced ? 4)12.2 grams of P 2 O 5 are formed from 3.4 grams of O 2 I just didn't know if This will involve several conversions of mass to moles and moles to Elemental P requires another step The guarantee is expressed as phosphate (P2O5). Each P2O5 molecule consists of 7 atoms (2P and 5O). the moles of H3PO4 to mol of P2O5 by writing a balanced equation. How many moles of P2O5 are formed from 3.4 grams of O2? About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Just want to know how i would go about this question, where would I start. EDIT: Converting to mass, you do get 369 g of P2O5 (you were right!) A 70% $\ce{P2O5}$ solution in water means 70 g $\ce{P2O5}$ is present in 100 grams of solution. 1 mol $\ce{P2O5}$ = 2 mol $\ce{H3PO4}$ and do wt percentage conversions to moles. However, there is no need to convert back to moles. Compare this with the manufacturer's specification. In Part B, you found the number of moles of product (3.00 mol P2O5mol P2O5 ) formed from the given amount of oxygen and excess phosphorus. One mole of P2O5 would be 6.022 x 1023 molecules of P2O5. I got the answer to that and it is P2O5. O from a known quantity of plant food. (6.6 grams) and H2O was 55.2 grams. Start studying Stoichiometry. Do mol conversions. You already had it in moles (2.60 mol) ... you needed this number to convert to mass. Then, use the balanced chemical equations to back-track from the mass of the precipitate to the mass of the P2O5. c) How many atoms are in 71.9 g of lithium hypochlorite (LiClO)? Now, determine the number of moles of P2O5P2O5 is produced from the givenand a) How many total atoms are in 0.600 g of P2O5? 2) 0.0078 moles of Cl 2 are needed to react with 1.25g of TiO 2.3) 0.023 moles of C are needed to react with 1.25g of TiO 2. No of moles=given mass÷molar mass 0.0250=given mass÷31×2+16×5 Given mass=142×0.025 Hence mass of 0.025 moles of P2O5 is 3.55g Answer: 1.808 moles Explanation: The equation is: - 4P + 5 O2 = 2 P2O5 Number of moles = Mass of substance / Mass of one mole Given, mass of P₄ = 112 g Mass of one mole of P₄ = 30.97 g/mol So, number of moles of P₄ How many molecules are in 38.5 g of carbon dioxide? Take the number of grams and divide it by the atomic mass. moles P2O5 = 1.098 x 2 = 2.195 moles P2O5 RomeliaThurston RomeliaThurston Answer: The maximum number of moles of theoretically made is 2.194 moles. Part A What is the maximum amount in moles of P2O5 that can theoretically be made from 161 g of P4 and excess oxygen? so the asked by Franki on February 5, 2008 Now, determine the number of moles of P2O5 is produced from the given amounts of phosphorus and oxygen. We need to find out how much P is in P2O5. The next step shows you that P2O5 is 43.7% P. Atomic weight: P = 31 O = 16 P 2: two of them so 2 X 31 = 62g Express your answer to three significant figures and include the appropriate units. Show the math below. 5O2 + P4 = 2 P2O5 We start with the initial amount of the limiting reactant which is oxygen and relate the substances from the chemical reaction to determine the maximum amount of P2O5 produced.
