The formula of the compound indicates that it contains ethylenediamine (en), sulfate (SO4), and chromium (Cr). The chromium ion has a +2 charge as it is balanced by two ethylenediamine ligands and two aqua (water) ligands, confirming that the compound is a chromium(II) complex. Therefore, the correct formula is diaquabis(ethylenediamine)chromium(II)sulfate.
