molar mass AlF3 = 83.98 g/mole33.4 g AlF3 x 1 mole/83.98 g = 0.398 moles
Each mole of AlF3 contains 3 moles of F- anions, because AlF3 ==> Al^3+ + 3F^-.
Thus, moles of anions = 3 x 0.398 = 1.19 moles of anions

How far away is lighting if heard ten seconds later?
sound travels at 334 metres per second, so 3.34 kilometres away
When 1 gram of liquid water at 0 degrees celsius freezes to form ice how many total joules of heat are lost by the water?
a change from liquid to solid or solid to liquid will require the use of the formula of Heat of Fusion , q=mHf where m is the mass and Hf = 334J/g, this is standard so you wont have to look for how it came about.In this case the m=5.00g so: q = m Hf q=(5.00g)(334 J/g) , you notice the grams will cancel out. q = 1670 J.
When 1 gram of water at 0 degrees Celsius freezes to form ice how many total joules of heat are lost by the water?
It's necessary to remove 540 calories from a gram of water in order to freeze it. That's about 2260 joules. The amount of energy used by a freezer to do this depends on the efficiency of the freezer.
How much heat energy must be absorbed to completely melt 35 grams of h2o at o degrees?
it will be 11,700J since the formula would be: q=mHf=35g x 334 J/g= 11,700 J
How much heat would your body lose if you were to ingest 1.00kg of snow at 273K to quench your thirst assume body temperature is 37 C and the amount of heat necessary to melt snow is 6.01 kj mol?
melt snow = 1000g*1mol/18.02g*6.01kj/mol=333.5kj=334 kj warm up H_2_O = q=mST= (1000G)(4.184 J/g *C)(37-0)=154808J=155KJ TOTAL 334KJ+155KJ=489KJ
