Mole concept - PLS help
Q- (100gm of CuSO4 . 5 H2O is dissolved in 500 g of water to form aq solution. find molarity & molality of Cu2+ if density of solution is 1.2 g/ml [Cu=64] [S=96])
isme sir ne bola water of crystallisation ka bhi mass lena hoga molality find krne ke liye or usme unhone water of crystallisation ke 2.5 mole liye , ye smajh nhi aaya
