Convert the scientific notation to a decimal number. Type the correct answer in the box. 4 × 10-5 cm = cm

MakcuM [25]

Answer:

$4 * 10^{-5}cm = 0.00004cm$

Explanation:

Given

$4 * 10^{-5}cm = [\ ]cm$

Required

Solve

Apply law of indices

$4 * \frac{1}{10^5}cm = [\ ]cm$

Evaluate 10^5

$4 * \frac{1}{100000}cm = [\ ]cm$

$4 * 0.00001cm = [\ ]cm$

$0.00004cm = [\ ]cm$

Hence:

$4 * 10^{-5}cm = 0.00004cm$

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
