Chemistry - Mole calculation help!?

Calculate the moles of aluminum contained in a 1.5g piece of scrap aluminum.Please and thanks! If you could explain how you got your answer, it would be super helpful!


If you look at a periodic table, you can determine the molar mass of aluminum, you will be able to determine that a mole of aluminum contains 26.98 gramsFrom there on, its a matter of a simple conversion 1.5 g Al ( 1 mole/26.98 g Al)The grams cancel out and you are left with .0559 molesWe need two significant digits according to the information you provided, so round to two placesThe answer is .06 mole
Depending on the boat, it's more difficult than a similar size power boatBut Jack stands are neededand these can add significant cost ($100 to $300 each) If you can edit your question, I'm sure the answers will be more accurateIt's doable but a hoist and crane is very helpfulYears ago we would hire a crane service to lift boats off the tractor trailers, and it wasn't that bad.about $75 each or $350 for the complete loadGood Luck!
Depending on the size small an A frame to a craneSafety first
FIRST you build a frame like a large open box out of 2x4's or 4x4's if the boat is really heavyThink of a TRAVEL LIFT because that is what it's going to look likeexcept it won't have to move and you are building out of woodthen you put a cross gracing over the bow and over the sternOnce you get a frame build, then put the boat and trailer inside it and LIFT THE BOAT AND TARILER by jacking the TRAILERonce you get the tariler up about 6 inches or so off the ground then use straps to secure the boat to the fore and aft framesthen lower the trailer and pull it clearthis will leave the boat hanging on the straps and off the frameIt's just like a travel lift except it doesn't movebut the lifting and storage is the same You are now free to flock the boat or not depending on your needsI have used rigs like this for years on boats up to about 10 tons and the only thing that changes is the size of the lumber I use.
