How many moles of water are contained in 0.250 mol of CuSo4 x 5H2O?
5*.250
1.25
4.15*10-25 power
To calculate the number of moles of water in a compound, you need to determine the coefficient of water in the chemical formula of the compound. In this case, the chemical formula for copper sulfate pentahydrate is CuSO4 • 5H2O.
The coefficient in front of H2O indicates that there are 5 moles of water for every 1 mole of CuSO4.
Therefore, if you have 0.250 mol of CuSO4 • 5H2O, you can calculate the number of moles of water by multiplying 0.250 mol by the coefficient of water:
0.250 mol CuSO4 • 5H2O * 5 mol H2O / 1 mol CuSO4 • 5H2O = 1.250 mol H2O
So, there are 1.250 moles of water in 0.250 mol of CuSO4 • 5H2O.
