First issues first, what number moles of (NH4)2CO3 do you have in 0.573 grams? moles = grams you have/ molecular mass in grams. 2d seem at stoichiometry. what number ammonium ions are there in each and each molecule of (NH4)2CO3? (ammonium ion = NH4+) Multiply the moles of ammonium carbonate by ability of the style of ammonium ions in each and each molecule of ammonium carbonate to confirm the style of moles of ammonium ion in the pattern. the different submit (by ability of Steve D) is right in determining the moles of entire compound, yet you want the moles of ammonium ion so verify you're taking the stoichiometry into consideration!!! examine the two PARAGRAPHS ABOVE THIS!!!!! STOICHIOMETRY!
