What is the minimum amount of 5.9M M H 2 SO 4 necessary to produce 26.7g of H 2 (g) according to the following reaction? 2Al(s)+3H 2 SO 4 (aq)�¨Al 2 (SO 4 ) 3 (aq)+3H 2 (g)
Convert 26.7 g H2SO4 to mols mol = grams/molar mass.
Using the coefficients in the balanced equation, convert mols H2 to mols H2SO4.
Then M x L = mols You know mols H2SO4 and M, sove for L.
