Jan 11, 2017 · 1.2 xx 10^23 molecules. The SAME number of molecules are in ANY “mole” of a compound or element. So, you only need to multiply the number of moles given by Avogadro's Number to find how many molecules there are. Moles are calculated from the molecular weight. For FeF_3 this would be 55.8 + 3*19 = "116 g/mole" "24 g" / "116 g/mol" = "0.207 moles of FeF"_3 "0.207 moles" xx 6.022 xx 10^23 ... Babylonian religion pdf

a) 0.22 L b) 0.44 L c) 0.56 L. Correct. The equation: Fe 3 O 4 + H 2 → 3 FeO + H 2 O. shows a one to one mole ratio between Fe 3 O 4 and H 2. 2.3 g of Fe 3 O 4 is 0.01 mole (molar mass = 231 g/mole) and therefore 0.01 mole of H 2 is required. At STP 0.01 mole is 0.01 x 22.4 L/mole = 0.22 L. Incorrect.
