You need to balance the equation.
2Al + 3H2SO4 ==> Al2(SO4)3 + 3H2
Now use the coefficients to convert mols Al to mols H2.
mols H2 = mols Al x (3 mols H2/2 mols Al) = ??
Note how the mols Al cancel to leave mols H2. That is how you know if the conversion factor you are using is the right one (instead of using 2 mols Al/3 mols H2.
Use the equation below to answer the following questions.
Al + H2SO4 ==> Al2(SO4)3 + H2
A. If 8.15 moles of aluminum are reacted, how many moles of hydrogen will be produced?
B. If 44.7 g of hydrogen sulfate is reacted, what mass of aluminum sulfate is produced?
C. If 34.6 g of hydrogen sulfate is reacted, how many moles of aluminum is also reacted?
D. What mass of aluminum is needed to produce 0.321 moles of hydrogen?
