What is the simplest formula for a compound containing 0.50 mol na?

The simplest formula for a compound containing 0.50 mol of Na (sodium) depends on the other element(s) present in the compound. If the compound contains only one more type of element and the ratio of Na to this element is 1:1, then the simplest formula would be NaX, where X represents the other element. If, for example, the compound contains 0.50 mol of Na and 0.50 mol of Cl (chlorine), the simplest formula would be NaCl. However, if the compound contains more than one type of element and/or the ratio of Na to another element is not 1:1, then the simplest formula would need to be determined using the molar ratios of each element in the compound.
