After the water is boiled off, the mass is 9.7 grams, so find the weight of the water.
12.98 - 9.7 = 3.28g H2O
Find how many moles of CuSO4 and H2O you have.
If there are about 18g per mole of H2O
3.28/18 = .1822 moles of H2O
If there are about 160g per mole of CuSO4
9.7/160 = .0606 moles of CuSO4
.1822/.0606 = 3
Ratio of H2O to CuSO4 = 1:3
Formula
<span>CuSO4.3H2O
</span>
Full Name
<span>Copper (II) Sulphate Trihydrate</span>

The object of anthropology is human in society ethnicity, culture and temperament. The science of anthropology has the purpose to study the human being in society tribes, behaved and cultured to build community itself<span>.</span></span>
The specific heat capacity of the metal is calculated as follows
heat energy = Mc delta T
heat energy (Q) = (711 j )
m=mass (41.1 g)
c= specific heat capacity =?
delta t = change in temperature( 94 -22=72)
c= Q/m delta T
c=711 j / (41.1 g x72) = 0.240 j/g /k
