The proportion is 2.9/3.1=0.935
The percentage is 0.935*100=93.5
Answer:
![m_{air}=3.6g](https://tex.z-dn.net/?f=m_%7Bair%7D%3D3.6g)
Explanation:
Hello,
In this case, given the law of conservation of mass which states that mass cannot be created nor destroyed, since the produced mass of the compound is 15.9 g and the mass of the initial substance is 12.3 g we obtain the mass of air by applying the following equation:
![m_{reactants}=m_{products}\\\\m_{substance}+m_{air}=m_{product}](https://tex.z-dn.net/?f=m_%7Breactants%7D%3Dm_%7Bproducts%7D%5C%5C%5C%5Cm_%7Bsubstance%7D%2Bm_%7Bair%7D%3Dm_%7Bproduct%7D)
Thus, solving for the mass of air we obtain:
![m_{air}=m_{product}-m_{substance}\\\\m_{air}=15.9g-12.3g\\\\m_{air}=3.6g](https://tex.z-dn.net/?f=m_%7Bair%7D%3Dm_%7Bproduct%7D-m_%7Bsubstance%7D%5C%5C%5C%5Cm_%7Bair%7D%3D15.9g-12.3g%5C%5C%5C%5Cm_%7Bair%7D%3D3.6g)
