Question

Suppose 1.1854g of copper(II) sulfate pentahydrate is heated to drive off the water of crystallization. Calculate what mass of water would be expected to be released from the salt

Answer 1

i got 0.668 g H20, but my lab partner calculated 0.4277 g? so idk who's right?

Answer 2

@iambatman can you help me? :)

Answer 3

show it

Answer 4

ok give me a min
