Answer:

The answer is

<h2>0.0056 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

volume = 3.4 mL

1 mg = 0.001 g

18.99 mg = 0.01899 g

So we have

density =  \frac{0.01899}{3.4}  \\  = 0.005585294..

We have the final answer as

<h3>0.0056 g/mL</h3>

Hope this helps you

Calculate the number of different atoms in 0.2 mol ethene​
muminat

Answer:

1.204 × 10²³

Explanation:

The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.

To convert moles to atoms, multiply the molar amount by Avogadro's number.

(6.022 × 10²³) × 0.2

         = 1.204 × 10²³

Oxygen, o, (number 8), sulfur, s, (number 16), and selenium, se, (number 34) have such similar chemical properties because?
irga5000 [103]

Oxygen (O), Sulphur (S) and Selenium (Se) have similar chemical properties because they all have the same number of electrons in their outermost shells.

Atoms with the same number of electrons in their outermost shells can be found in the same group.

A group consists of elements arranged in the same column (from top to bottom) on the periodic table. Elements on the same group have similar chemical properties.

Oxygen (O), Sulphur (S) and Selenium (Se) are in group eight. All three elements are highly electronegative and have 6 electrons in their outermost shell. They also carry ab charge of -2.
