(Pre-Lab Questions)
1. Calculate the amount in moles and the mass in grams of KOH needed to convert 1.50 g of aluminum to KAl(OH)4.
Write the balanced equation first.
2. Calculate the volume (in mL) of 9.0M H2SO4 that you would need to convert 0.070 moles of KAl(OH)4 to K2SO4 and Al2(SO4)3 according to the following equation:
2 KAl(OH)4 + 4 H2SO4 = ?K2SO4 + Al2(SO4)3 + 8 H2O
3. How many moles and how many grams of potassium alum, KAl(SO4)2 · 12 H2O, can be prepared from 5.00 g of aluminum?
Thanks in Advance for your help, the instructions aren't very clear in this pre-lab.
