Answer:
Decrease by the distance squared
Explanation:
<u><em>Gravitation formula:</em></u>
where
'F' is the force of attraction between the two bodies (Gravitational force),
'G' is the universal gravitational constant,
'M' is the mass of the first object,
'm' is the mass of the second object and
'r' is the distance between the centers of each object.
Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
Answer:
The answer is "2.5 mole"
Explanation:
The reaction for producing can be defined as follows:
Reaction:
According to the above reaction, to produce 2 moles of we need 1 mole of nitrogen:
So, according to the question to produce 5.0 mole the required
:
To produce 5.0 mole we need 2.5 mole
Answer: Therefore, the concentration of final solution is
Explanation:
According to the neutralization law,
where,
= molarity of stock solution =
= volume of stock solution = 3.00 ml
= molarity of diluted solution = ?
= volume of diluted solution = 25.00 ml
Therefore, the concentration of diluted solution is
2) On further dilution
where,
= molarity of stock solution =
= volume of stock solution = 3.00 ml
= molarity of diluted solution = ?
= volume of diluted solution = 25.00 ml
Therefore, the concentration of diluted solution is
3) On further dilution
where,
= molarity of stock solution =
= volume of stock solution = 3.00 ml
= molarity of diluted solution = ?
= volume of diluted solution = 25.00 ml
Therefore, the concentration of final solution is
Answer:
Density of aluminum is 2.699 g/cm^3
Explanation:
Density of a given material can be defined as the mass of the substance present in a unit volume. Mathematically it can be expressed as:
Units: g/cm^3 or kg/m^3
Aluminum (Al) is one the lightest element and is known to have a density of 2.699 g/cm^3
