Calculate the density of a material that has a mass of 52.457 g and a volume of 13.5 cm^3. The formula is D=m/v
Answer:
The answer is
3.89 g/cm³Explanation:
The Density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} [/tex]
From the question
mass = 52.457 g
volume = 13.5 cm³
The density is
[tex]density = \frac{52.457}{13.5} \\ = 3.885703...[/tex]
We have the final answer as
3.89 g/cm³Hope this helps you

Explanation:
Calculate the mass of a piece of metal if its volume is 2.3 cm’and density is .486 g/cm3.
<-- Round to 3 digits
and show correct
units
Answer:
1.12 g.
Explanation:
From the question given above, the following were obtained obtained:
Volume (V) of metal = 2.3 cm³
Density (D) of metal = 0.486 g/cm³
Mass (m) of metal =..?
The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:
Density (D) = mass (m) / volume (V)
D = m/V
With the above formula, we can easily calculate the mass of the metal as shown below:
Volume (V) of metal = 2.3 cm³
Density (D) of metal = 0.486 g/cm³
Mass (m) of metal =..?
D = m/V
0.486 = m/2.3
Cross multiply
m = 0.486 × 2.3
m = 1.12 g
Therefore, the mass of the metal is 1.12 g.

Which groups of the periodic table want to gain electrons? What kind(s) of elements are these groups
Answer:
Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.
Explanation:
The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.
The periodic table is composed of 18 groups and 8 periods of elements. Groups 1 - 13 are metals while groups 15 -18 are nonmetals. Group 14 consists of a mixture of metals and nonmetals.
The nonmetals usually accept electrons while metals electrons easily donate electrons. Elements of group 18 neither receive nor donate electrons because they have a complete octet.
Nonmetals of groups 15 -17 gain electrons easily.

ANALYZE A ball of clay is manipulated into different shapes in each of the images
below. Does the amount of mass and matter in each of the images below change as
the size and shape of the clay ball is changed? Explain your reasoning.
Answer:
The amount of mass and matter in all the transformations of the clay ball will remain the same or constant
Explanation:
From the law of conservation of mass we have, for an enclosed system to and from which there is no transfer of matter or energy, mass cannot be created nor destroyed, and remains constant at the given value, but the matter which make up the mass can be changed into different forms
Therefore, the clay ball can be transformed into different shapes and will still posses the same initial mass before the transformation, provided there are no transfer of matter or energy from the clay ball system.

calculate the number of atoms of sodium in a 4.5-gram sample
Answer:
1.18×10²³ atoms.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms.
From the above concept, 1 mole of sodium also contains 6.02×10²³ atoms.
1 mole of sodium = 23 g.
Thus,
23 g of sodium contains 6.02×10²³ atoms.
Therefore, 4.5 g of sodium will contain = (4.5 × 6.02×10²³)/23 = 1.18×10²³ atoms.
From the above calculation,
4.5 g of sodium contains 1.18×10²³ atoms.
What does the force of gravity between two objects depend on?
A. The masses of the two objects and the distance between them
B. Only the mass of the smaller object and its distance from the
larger object
C. Only the masses of the two objects
D. The mass of the smaller object and the speed at which it's moving
Answer:
A
Explanation:
Answer:
Explanation:
The formula for the force of gravity is
F=G * m1 * m2 / r^2
G is a constant. It does not change with the use of the formula. There are 2 masses, so the force depends on the masses.
The right hand side is divided by r^2. that's a distance. So that's the other quantity influencing the Force.
B: incorrect. Both objects have masses. That determines the force between them.
C: incorrect. It's also the distance between them.
D: incorrect. The formula contains nothing to indicate that velocity is important.
The answer is A
What two-step process separated the cans into aluminum, steel, and tin?
Answer:
Magnet
Durability and heaviness.(texture)
Explanation:
Magnet can be use to separate Aluminum from mixture of steel and aluminum.
Though aluminum and steel look alike but magnet can be use to separate it.
If the can attract the magnet or magnet stick to the can, it is a steel can. Aluminum does not stick to magnet.
A mixture of Aluminum and tin can also be separated by magnet.
Tin attract magnet but tin is more durable, heavy and does not corrode easily.
When u touch the three cans, tin is heavy and durable.
