Calculate the number of grams of aluminum sulfate produced if three point 85 grams of aluminum is added to six point 85 grams of sulfuric acid.
2Al(s)+3H2SO4(aq)→Al2(SO4)3(aq)+3H2(g)Molar mass of Al= 26.98153985/26.981539= 3.15molMolar mass of H2SO4= 98.079 85/98.079= 0.87molMole ratio of Al:Al2(SO4)3= 2:1Mole ratio of H2SO4:Al2(SO4)3= 3:1= 1/2+1/3= 5/6Molar mass of Al2(SO4)3= 342.15 g/mol342.16×5/6= 285.13g

3.75M sulfuric acid solution that has a density of 1.23g/ml. Calculate the mass percent,molality and normality of sulfuric acid?H=1g/mol , O=16g/mol , S=32 g/mol
Solution:sulfuric acid = H2SO4The molar mass of H2SO4 = 2×Ar(H) + Ar(S) + 4×Ar(O) = 2×1 + 32 + 4×16 = 98 (g/mol).Suppose that the volume of the solution is...

There are 1000 liters in 1 cubic meter and 1000 grams in 1 kilogram. How many grams of air are in 1 liter of air? (Assume a density of 1.18 kg/m3.)
Solution: There are 1000 liters in 1 cubic meter, it means that volume and mass of 1 liter is 1/1000, or 0.001 of 1 cubic meter. Then: Mass of 1...

A solution of sulfuric acid was made by dissolving 20 grams of 98 percent sulfuric acid in 250 ml of water. Express the concentration of this solution in percent by weight
98% sulphuric acid means in 100 g sulphuric acid source exact amount of sulphuric acid, H2SO4 present 98 g. So in 20 g, exact amount of H2SO4 present =...

Calcium sulfate is produced by reacting copper with sulfuric acid. If 40 kg of sulfuric acid were used, what is the weight of copper, in grams, required for the reaction?
[By calcium sulfate I believe is meant copper sulfate?]Cu + 2H2SO4 —> CuSO4 + SO2 + 2H2OMass of sulfuric acid = 40kg = 40000gMolar mass of sulfuric acid = 196g/mol∴...
