As you know the density of pure water is 1 g/ml. so the mass of 250 ml water is 250 g.
Now the no of molecules of water present in 250 g of water = 250 x 6 x 1023/18 = 8.33 x 1024
Now each molecule of water contains total 10 electron. So total no. of electrons in 250 g of water are 10 x 8.33 x 1024 = 8.33 x 1025 electrons.

How do you calculate 250 ppm chlorine solution in water?
To calculate 250 ppm (parts per million) chlorine solution in water, you would need 250 parts of chlorine for every 1 million parts of water. This can be simplified to 1 part of chlorine for every 4000 parts of water (since 1 million divided by 250 is 4000). Therefore, you would mix 1 unit of chlorine with 4000 units of water to achieve a 250 ppm chlorine solution.
