Calculate the solubility in mol/dm3 of 40g CUSO4 dissolved in 100g of H2O at 120°c
Accepted Answer
Calculate the solubility of 40g CuSO4 dissolved in 100g of H2O at 120°C
1. Calculate the moles of CuSO4 dissolved
moles of CuSO4 = 40 g / 159.6 g/mol = 0.251 mol
2. Calculate the mass of the solution
mass of solution = 100 g H2O + 40 g CuSO4 = 140 g
3. Calculate the molarity
molarity = moles of CuSO4 / liters of solution
First, convert the mass of the solution to liters by dividing by the density of water (1 g/mL):
volume of solution = 140 g / 1 g/mL = 140 mL = 0.14 L
Now, calculate the molarity:
molarity = 0.251 mol / 0.14 L = 1.79 mol/dm3
Therefore, at 120°C, the solubility of CuSO4 in water is 1.79 mol/dm3.
