Answer:
<em>Density = 1.74 gm/mL</em>
Explanation:
Given that:
Mass of piece of Magnesium = 4.80 grams
The volume displaced by this piece = 2.76mL
Let us learn about a property:
Volume of water displaced by a substance when immersed in the water is equal to the Volume of the substance itself.
So, volume of the piece of Magnesium = 2.76 mL
To find:
Density of magnesium = ?
Solution:
Let us have a look at the formula for Density of a Substance:
Density of a substance is given as the ratio of mass of substance and the volume of that mass of substance.
i.e.
Putting the given values:
So, the answer is:
Density of Magnesium = <em>1.74 gm/mL</em>

One atom is a metal and one is a nonmetal.
One atom has high electronegativity value, while the other value is really low
Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 
.
<u>Given the following data:</u>
- Mass of box = 50 kilogram
To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;
Making acceleration the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Acceleration = 0.5
