Question

How many grams of water can be produced in the combination of
24.7 grams oxygen gas and 14 grams hydrogen gas? ​

Answer 1

If 14 grams of hydrogen reacted with 24.7 grams of oxygen 27.7875 grams of water will be formed.

Explanation:

2H2+O2----------->2H2O.

• From the above equation, we can say that 4g of Hydrogen will react with 32 g of oxygen.

• In this question, Hydrogen is in excess amount.

• 32 g of Oxygen will react with = 4 g of H2.

• Therefore 24.7g of Oxygen will react with =24.7x4/32= 3.0875 g H2.  

• The remaining 10.9125g of H2 will be left unreacted.

• Therefore the amount of water formed=(24.7+3.0875)=27.7875 g
