SrH2 + 2 H2O ==> Sr(OH)2 + 2 H2
Determine the number of grams of strontium hydroxide (Sr(OH)2) produced when 10.0 g of hydrogen gas (H2) is also produced. (Your answer must have at least 3 significant figures.)
mols H2 gas = grams/molar mass
Convert mols H2 to mols Sr(OH)2 using the coefficients in the balanced equation.
Convert mols Sr(OH)2 to grams. g = mols x molar mass.
