How many grams of water can be produced when 11.7 moles of ethane (C2H6) react with excess oxygen gas?
Elina [12.6K]

Answer: 631.8 g

Explanation:

2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O

It can be seen from the balanced chemical equation, 2 moles of ethane reacts with 7 moles of Oxygen gas to produce 4 moles of carbon dioxide and 6 moles of water.

Ethane is the limiting reagent as it limits the formation of product.

Thus, if  2 moles of ethane produce 6 moles of water.

11.7 moles moles of ethane produce=\frac{6}{2}\times 11.7=35.1 molesof water.

Mass of water= no of moles\times Molar mass

Mass of water= 35.1\times 18g/mol= 631.8 g
