Your crucible has a mass of 30.074 g when empty, and does not change upon heating. You add some solid iron and then weigh the crucible and iron to be 32.860 g together. You then burn the iron in the presence of oxygen following the procedure in the handout. Assume that there are no contaminates and all of the iron is converted to iron oxide. The final mass of the crucible and iron oxide is 33.961 g, which does not change upon heating. The unrounded empirical formula obtained from these measurements would be FeOX, where X is a decimal type number (not necessarily a whole number). Give the value of X in the blank below in decimal format with the correct number of significant figures
