Hi Candidate,

1Gallon refers to 3.745 Litres. To be exact, 1 liter is 0.264 gallon (a little more than a quart), and 4 liters is 1.06 gallons.

In the given Question, it's mentioned that in one tablet, 17.5 gram of KMnO4 is present in 1 Litre of solution of KMnO4. To prepare 1 in 500 solution of 1 gallon, the number of tablet required= 4.75/17.5 ×500= 135.71 tablets or about 136 tablets.

Hope that this answer helps you.
