Using 50g of sand , clay and loam and 80 ml was run through each soil and soil C's amount of water drained through it is 25ml how much water was retained by soil C?

To find out how much water was retained by soil C, we need to subtract the amount of water drained through it from the total amount of water that was run through it.

Total amount of water run through soil C = 80 ml
Amount of water drained through soil C = 25 ml

Water retained by soil C = Total amount of water run through soil C - Amount of water drained through soil C
Water retained by soil C = 80 ml - 25 ml
Water retained by soil C = 55 ml

Therefore, soil C retained 55 ml of water.
