41. Conclusion One
The concentration of copper(II) nitrate in
sample A is 0.218 mol/L

42. Conclusion Two
The concentration of copper(II) nitrate in
sample B is 0.410 mol/L

43. Conclusion Three
The first equation, y = f(x), is
y = - 0.148 + 2.488 x

44. Conclusion Four
The other equation, x = f(y) is
x = 0.05948 + 0.4019 y
