Answer» mol. wt of X4O6 = 4* atomic mass of X + 6 * atomic mass of O = 4x + 6*16 = 4x+96..where x is atomic mass of element X.so 4x+96 gms of X4O6 contains 4x gms of X.given, 10 g X4O6 contains 5.72 gms of X.so we can write, 4x+96 / 10 = 4x/5.72.solve the equtaion for x .by solving u can getx= 32.074 (answer ) |
