Concentration of the solution (% mass) = 4%
<h3>Further explanation</h3><em>Rosa prepared a salt water solution by mixing 120 mg of water with 5 mg of common salt, what concentration is the solution she prepare?</em>
<em />
<em /><em />
mass solute=mass of salt=5 mg
mass solution :
mass solute(salt)+mass solvent(water) :
The mass of nitroglycerin : 34.52 g
<h3>Further explanation</h3>Reaction
4C₃H₅N₃O₉ ⇒ 12 CO₂ + 10H₂O + 6N₂ +O₂
Volume = 10 L
Temperature = -5°C=268 °K
Pressure = 1 atm
mol of CO₂ (ideal gas) :
mol ratio C₃H₅N₃O₉ : mol CO₂= 4 : 12, so mol C₃H₅N₃O₉ :
mass C₃H₅N₃O₉ (MW=227,0865 g/mol):
