Answer:
11.3 g.
Explanation:
Hello there!
In this case, since the combustion of butane is:
![C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O](https://tex.z-dn.net/?f=C_4H_%7B10%7D%2B%5Cfrac%7B13%7D%7B2%7D%20O_2%5Crightarrow%204CO_2%2B5H_2O)
Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:
![m_{H_2O}=7.26gC_4H_{10}*\frac{1molC_4H_{10}}{58.14gC_4H_{10}}*\frac{5molH_2O}{1molC_4H_{10}} *\frac{18.02gH_2O}{1molH_2O}](https://tex.z-dn.net/?f=m_%7BH_2O%7D%3D7.26gC_4H_%7B10%7D%2A%5Cfrac%7B1molC_4H_%7B10%7D%7D%7B58.14gC_4H_%7B10%7D%7D%2A%5Cfrac%7B5molH_2O%7D%7B1molC_4H_%7B10%7D%7D%20%20%2A%5Cfrac%7B18.02gH_2O%7D%7B1molH_2O%7D)
Therefore, the resulting mass of water is:
![m_{H_2O}=11.3gH_2O](https://tex.z-dn.net/?f=m_%7BH_2O%7D%3D11.3gH_2O)
