No of atoms in 4.8 dm³ of neon gas is determined in the following way.
Explanation:
We have given
Neon Gas=4.8dm³
At STP
1 mole of an ideal gas occupies 22.4 L(dm³) of volume.
which means that number of molecules occupy 22.4 L of volume.
So
4.8 dm³x 1 mole/22.4 dm³ = 0.214 moles Neon
0.214 moles x 6.02x10²³ atoms/mole = 1.29x10²³ atoms of Neon
No of Atoms in 4.8dm3 neon gas =1.29x10²³ atoms of Neon

Even though an atom may be smaller than another atom, it might have more mass. The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the object divided by its volume; D = m/v. Objects with the same mass but different volume have different densities.
The mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.
<h3>How to calculate mass?</h3>
The mass of an object can be calculated using the following formula:
F = ma
Where;
- F = force (N)
- m = mass (kg)
- a = acceleration (m/s²)
m = F/a
m = 356/4
m = 89kg
Therefore, the mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.
