If 1.50 grams of aluminum hydroxide reacts with 2.55 grams of sulfuric acid, how many grams of water are formed? Molar mass aluminum hydroxide = 78.00 g/mol, molar mass of sulfuric acid =
98.08 g/mol, molar mass water = 18.02 g/mol. Use correct significant figures and units in your
answer.
2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6 H2O

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
