If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.
With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).
The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.
If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.

You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.
3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
The question asks us to find that 12 fl oz is equivalent to 335 ml. Then we have to either convert the milliliter to oz or vice-verse. In this case we will convert 12 fl oz to milleter and check if it comes to 335 ml.
Now we already know that
1 oz = 29.57 ml
Then
12 oz = (29.57 * 12) ml
= 354.84 ml
= 355 ml
So we see that 12 oz is not equal to 335 ml but it is almost equivalent to 335 ml.
