Density is mass divided by volume. Therefore, volume is mass divided by density.

<h2>
Hello!</h2>
The answer is:
The new volume will be 1 L.

<h2>
Why?</h2>
To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.
To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.
Boyle's Law equation is:

So, we are given the information:

Then, isolating the new volume and substituting into the equation, we have:



Hence, the new volume will be 1 L.

Have a nice day!
That element is manganese. As they are in same horizontal row (period) and are next to each other. That is why they show same properties.
Hope this helps xox :)
Answer:
Electrons
Explanation:
Because the nucleas is In the middle and the Electrons surround it
Answer:
4 moles of neon
Explanation:
Given data:
Number of moles of neon = ?
Number of atoms of neon = 2.4×10²⁴ atoms
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For given neon atoms:
1 mol = 6.022 × 10²³ atoms
2.4×10²⁴ atoms × 1 mol / 6.022 × 10²³ atoms
0.4×10¹ mol = 4 mol
