The gram molecular mass of CuSO₄.5H₂O is 249.5 grams(1mole)
In it there are 5 molecules of water weighing 90 grams.
Now,
499 grams of CuSO₄.5H₂O indicates 2 moles of it.
so the mass of water present = 90 x 2 = 180 grams
In it there are 5 molecules of water weighing 90 grams.
Now,
499 grams of CuSO₄.5H₂O indicates 2 moles of it.
so the mass of water present = 90 x 2 = 180 grams

thanks
did u get it
yea but how does 499 gm of cuso4.5h20 contains 2 mole of oxygen
not 2 moles of oxygen....
number of moles in 499 grams = 499/249.5 = 2
it is the number of moles of CuSO4.5H2O
oh means 2 moles of cuso4.5h20
i understood
ty again
welcome
