Question

Given the chemical reaction below, how many mL of ammonia are required to completely react with 1.20 g of CuSO4? (density of ammonia = 0.252 g/mL)

CuSO4 + 4 NH3 + H2O [Cu(NH3)4]SO4.H2O

Answer 1

Hey there!

We'll have to convert grams to moles first. Can you find the molar mass of CuSO4 first?

Then we can find how many miles of ammonia we would need to completely react with CuSO4

And then we can convert the moles to grams using ammonia's molar mass
And then using the density, we can find how many mL of ammonia we will need

So first, can you find how many moles of CuSO4 we're starting off with?
