A student places 1.520 grams of copper wire along with excess sulfur into a crucible (and cover), which weighs 18.030 g empty. The contents are heated mildly for five minutes to allow all the copper to react. The contents are then heated to glowing red heat for another five minutes to remove excess sulfur. The crucible and contents are cooled to room temperature. Calculate the mass of the excess sulfur (prior to its removal) if 0.4546 g of sulfur was put into the crucible at the start of the reaction. Molar Mass Cu: 63.55 g/mole Molar Mass S: 32.10 g/mole
