Hello dear student


1 mole of water weighs = the molecular mass of water.

thus the amount of present in 0.25 mole of it is 4.5 grams

So ans a. 4.5 gm


or


mass of water - 0.25 mol


We know molecular mass of water ( M) = 18

No. Of grams ( W)  ?

No. Of moles = W/M

W= No of moles × M

W =  0.25 × 18

W= 4.5 gm


hope that's helpful


best of luck
