Question

A mixture of 130.7 g of P and 135.0 g of O, reacts completely to form P,0, and P,00 Find the masses of P,0, and P,0,0 that are formed by the reaction. mass of P,0, mass of P,00

Answer 1

The calculation is attached below :

The reaction can be written as -- 489 +802 - PA Oo + PAOIO 31 32 Molecular weight of p = 319. Molecular weight of O2 = 32 g. Molecular weight of Paque = 219.889 Molecular weight of PA 010 = 283.88 g. de Amount of p taken = 130.7 g. Antount at No. of moles of p= 130:70. 4.218 moles. Amount of Oz taken = 135 g. No. of moles of 02 = 135 = 4.21 moles: No. of moles of PA Oo alto x 4.21) = 0.52625.moles. 3 Amount of PA OG = (0.52625% 219.88) g. = 115.71 g * No. of moles of PA 0,6 = H x 4-21) = 0,52625 moles. 44 Amount of PAOLO = (0.52625X283.88) g E = 149.39 gi G Am o Amo Man of PA Oo used is 115.71g and Palic meck is 149.39 g.
