Answer:

7.8 × 10∧-4 nm³

Explanation:

Given data:

volume = 7.8x10^-31 m^3

volume in nm³= ?

Solution:

I m³ = 1 × 10∧27

7.8 x 10^-31 × 1 × 10∧27 = 7.8 × 10∧-4 nm³

vichka [17]

Answer:

5.41 ×10⁻²²

Explanation:

We were told right from the question that both the Zinc ions and the Zinc oxide adopts a face-centered cubic arrangement.

Then, the number of ZnO molecule in one unit cell = 4

The standard molar mass of ZnO = 81.38g

Avogadro's constant = 6.023 × 10²³ mole

∴

The mass of one unit cell of zinc oxide can be calculated as:

= \frac{4*81.38}{6.023*10^{23}}

= 5.40461564×10⁻²²

≅ 5.41 ×10⁻²²

∴ The mass of one unit cell of zinc oxide = 5.41 ×10⁻²²

Explain why the noble gases tend not to react
harkovskaia [24]
The noble gases don't react because they have their full orbital. They have 8 valence electrons, meaning that they are happy and stable. They dont need any more electrons, which means that they dont need to bond. That makes them un- reactive.

What would the total mass of a 4.9 mole sample of Barium (Ba) be if its Molar Mass is 137g?
Aleksandr-060686 [28]

Answer:

m = 671 grams

Explanation:

Given that,

No of moles, n = 4.9

Molar mass of Barium, M = 137 g

Mass divided by molar mass is equal to no of moles. It can be given by the formula as follows :

n=\dfrac{m}{M}\\\\m=n\times M\\\\m=4.9\times 137\\\\m=671.3\ g

or

m = 671 grams

So, the total mass of the sample of Barium is 671 grams.
