Use the balanced equation given below to solve the problem that follows: Calculate the mass in grams of water produced along wit
saveliy_v [14]

Answer: 1.98 g

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given volume}}{\text{Molar volume}}  

\text{Moles of} CO_2=\frac{5.0L}{22.4L}=0.22moles

The balanced given equation is:

C_2H_2(g)+5O_2(g)\rightarrow 4CO_2(g)+2H_2O(g)  

According to stoichiometry :

4 moles of CO_2 will produce =  2 moles of H_2O

Thus 0.22 moles of CO_2 will produce=\frac{2}{4}\times 0.22=0.11moles  of H_2O

Mass of H_2O=moles\times {\text {Molar mass}}=0.11moles\times 18g/mol=1.98g

Thus 1.98 g of water is produced along with 5.0 L of CO_2 at STP
