A certain part of an aircraft engine has a volume of 1.6 ft3.(a) Find the weight of the piece when it is made of silver. lb(b) If the same piece is made of aluminum, what is its weight? lbDetermine how much weight is saved by using aluminum instead of silver. lb
What grade of aluminum? If we assume a standard 1100 Aluminum, The Engineers Toolbox lists the density as 2720 kg/m? as there are 0.062428 lb/ft? per kg/m? This converts to 169.8 lb/ft? The same source lists pure silver as 10490 kg/m? or 654.9lb/ft? (a) Find the weight of the piece when it is made of silver654.9 lb/ft?(1.6 ft?) 1047.84 lb Which carries way too much precision for the original numbers to support, but rounding to the limiting two significant figures might affect the intended lesson Let's just call it 1050 lb (b) If the same piece is made of aluminum, what is its weight? 169.8 lb/ft?(1.6 ft?) 271.68 Let's call it 272 lb Determine how much weight is saved by using aluminum instead of silver 1047.84 - 271.68 776.16 Let's call it 776 lb I hope this helpsPlease remember to vote a Best Answer from among your resultsIt's good karma as it helps keep the exchange in balance.
AlCl3 + Br2 - AlBr3 + Cl2 a millionstability: 2AlCl3 + 3Br2 - 2AlBr3 + 3Cl2 237.4 g of AlCl3 X ( a million mol of AlCl3 / 133.34 g of AlCl3 ) X ( 3 mol of Br2 / 2 mol of AlCl3 ) X ( 159.eighty two g of Br2 / a million mol of Br2 ) sixty seven.24 g of Br2
