You have the balanced equation. That's always the first step.
Convert 24.4 g Al to mols. mols = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols Al to mols H2SO4.
Now convert mols H2SO4 to grams. g = mols x molar mass = ?
Sulfuric acid can dissolve aluminum metal according to the following reaction.
2Al(s)+3H2SO4(aq)→Al2(SO4)3(aq)+3H2(g) Suppose you wanted to dissolve an aluminum block with a mass of 24.4g .
What minimum amount of H2SO4 in grams would you need?
