Hydrogen gas and nitrogen gas react to form ammonia gas. What volume of ammonia would be produced by this reaction if of hydrogen were consumed? Also, be sure your answer has a unit symbol, and is rounded to significant digits.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
