A. What mass of FeSO4 should they have weighed out to get 2.00 moles? B. How many moles of Fe2(SO), did they weigh out instead? 7 10 A A laboratory technician is asked to weigh out 2.00 moles of iron(1) sulfate, FeSO4. So they calculate the mass of FeSO4 they need to have 2.00 moles of the compound. However, in the dimly lit chemical stockroom they get confused and instead of grabbing the bottle of FeSO4, they grab a bottle of iron(1) sulfate. Fe₂(SO4)3 They then weigh out the same mass of Fe2(SO4), that would be 2.00 moles of Fe50 BIVALE X Paragon Rebu 184 Submit A forensic scientist is analyzing a sample of white powder found on someone who is suspected of dealing drugs.
