Answer:

  5

Step-by-step explanation:

Put the numbers where the corresponding variables are in the formula and do the arithmetic.

  0.3y+\dfrac{y}{z}=0.3\cdot 10+\dfrac{10}{5}=3+2=5

The expression evaluates to 5.

1. what would the effect have been on the calculated formula weight ([9] above) of your unknown as compared to the true formula
kramer

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.

What is the sum of (–6) + (–6) + (–6) + (–6) + (–6) + (–6)
nalin [4]

It looks like you've got six numbers lined up there, every one of them is the same number, and you need to have them added up.

Well, you've got (-6) listed six ==> <em>TIMES</em> <== , so the situation is the same as if you just wrote

6 x (-6)

and that's just <em>-36 </em>.
