How many moles of oxygen gas can be produced during electricity decomposition of 180 g of water ?

A

2.5 moles

B

5 moles

C

10 moles

D

7 moles

Text Solution

Verified by Experts

`underset(2xx18=36g)(2H_2O) to 2H_2 + O_2`
36 g of water produces 1 mole of `O_2` gas
180 g of water will produce 180/36 = 5 moles of `O_2` gas.
