According to the following reaction, how many grams of nitrogen gas will be formed upon the complete reaction of 22.2 grams of hydrogen gas with excess nitrogen monoxide?
nitrogen monoxide (g) + hydrogen (g) nitrogen (g) + water (l)
You need to write and balance the equation.
2NO + 2H2 ==> N2 + 2H2O
Convert 22.2 g H2 to mols. mols = grams/molar mass.
Use the coefficients in the balanced equation to convert mols H2 to mols N2.
Now convert mols N2 gas to grams. g = mols x molar mass.
