Weds 12-12 Complete test on balancing and chemical reactions
Answers to practice quiz questions on 12-20 are given here:
1) 285934 g 2) 1.406 moles
Here is how they are done: First find the formula of gallium iodide. It is GaI3
Then find the mass of 1 mole of GaI3. It is (1x 70 )+( 3 x 127) =70+381=451 g
Use 1 mole = 451 g as a conversion factor in both problems.
1) 634moles/1 x 451g/1mole = 285934 g (the moles cancel)
2) 634 g/1 x 1mole/451g = 1.406 moles (the grams cancel)
