@ 20 Celsius - 22g CuSO4 / 100g H2O
@ 40 Celsius- 42g CuSO4 / 100g H2O

Using this, answer whether these are saturated or unsaturated

@ 40 Celsius is 5g CuSO4 / 10g H2O

@ 40 Celsius is 99g CuSO4 / 250g H2)

I was told that the first one is unsaturated and the second one is saturated but...I come up the opposite of what I was told....Help please!
