Convert 500 g urea to mols. mols = grams/molar mass.
Convert mols urea to mols NH3 using the coefficients in the balanced equation.
Use PV = nRT to convert mols NH3 at STP (mols you have from step 2) to mols NH3 at 25 C and 1.5 atm.
Post your work if you get stuck.
Urea, NH2CONH2, is manufactured from ammonia and carbon dioxide according to the following equation:
2 NH3 (g) + CO2 (g) -> NH2CONH2(aq)+ H2O (l)
What volume of ammonia gas at 25 o C and 1.5 atm is needed to make 500g of urea?
