Answer: The concentartion of solution will be 0.224 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute =
= volume of solution in ml = 275 ml
Now put all the given values in the formula of molarity, we get
Therefore, the concentration of solution will be 0.224 M
First, this would go under physics.
Gravity is a relatively weak force and depends on the mass and distance of two objects. Even between insects, the force of gravity exists. However, it is not strong enough to be present because the two masses are too small and too far away.
Here is a Harvard question that is similar.

If the universe started out so dense, why didn't it collapse into a black hole?
A large enough clump of matter will collapse to form a black hole, but ONLY if it is surrounded by (relatively) empty space. During the Big Bang, there WAS NO empty space: ALL of space was filled more or less uniformly with matter and energy; there was no "center of attraction" around which matter could coalesce. Under these circumstances, a cosmic-scale black hole will not form (and lucky for us!).
The mass of sample = 10 g
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/ml
m = mass , g
v = volume , ml
Density is 5 g/ml and sample is 2 ml,so :
ρ = 5 g/ml
V = 2 ml
The mass :
