uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuum i thinkitis the way its shaped
N(Na₂SO₄)=3 mol
n(O)=4n(Na₂SO₄)
n(O)=4*3=12 mol
Hello!
The reduction in particle size results in an increased rate of solution. It occur because is harder for a a solvent to surround bigger molecules.

Answer:
Speed of light
Explanation:
The value 3.0 x 10⁸m/s is taken as the speed of light.
It is a constant.
- It implies that light travels a distance of 3 x 10⁸ in just one second.
- This value is for the speed of light in a vacuum when there are not particles obstructing its movement.
- The speed of electromagnetic radiations in free space is also taken as the speed of light.
