Answer:
38.8 g
Explanation:
Density is just mass divided by volume, so if you know 2 of those 3 things you can solve for the other one.
Let's write it as: D = m/v
We know D, and we know v, so solve for m:
m = Dv
Now just plug in the the known values:
m = (0.98 g/ml)( 39.63 ml) = 38.8 g
(Notice how ml cancelled out, leaving grams, which is what we wanted for mass.)

A pitcher throws a ball toward a player holding a softballbat. The player uses the bat to hit the ball. The bat applies a 10-newton force to the ball. The statement correctly describes the reaction force between the bat and ball is the reaction force is the force applied to the bat by the player holding the bat. Therefore, option B is correct.
What do you mean by the force ?
The term force is defined as the push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. Force has a magnitude and a direction.
A force is a physicalquantity which cause a motion in an object at rest or changes to change the.The direction of motion of a moving object or the shape or size of the object.

Final answer:
A face centered cubic lattice consists of 4 atoms. The volume of the unit cell is 9.22 x 10^-23 cm^3 and the mass is 1.34 x 10^-23 g. The approximate atomic mass of the element is 2.02 amu.
Explanation:
The element is said to crystallize in a face centered cubic lattice. This implies that there is one atom at each corner of the cube (8 corners for a total of 1 atom, since each corner atom is shared among 8 adjacent cubes). There is also one atom on each face of the cube (6 faces for a total of 3 atoms, since each face atom is shared among 2 adjacent cubes). Thus, a total of 4 atoms are present in each unit cell. (a)
The volume of a unit cell (edges for a cube) can be calculated by the formula 'volume = side^3', where side in this case is 4.52 x 10-8cm. Hence, the volume equals (4.52 x 10^-8cm)^3 = 9.22 x 10^-23cm^3. (b)
The density of the substance is given as 1.45g/cm^3. The formula for density is 'mass/volume' which implies that mass can be calculated as 'density x volume'. Hence, the mass of the unit cell is (1.45g/cm^3) x (9.22 x 10^-23 cm^3) = 1.34 x 10^-23 g.(c)
The atomic weight of the element can then be calculated by taking this overall mass and dividing by the number of atoms in a unit cell (4). So, the atomic weight is (1.34 x 10^-23 g) / 4 = 3.35 x 10^-24 g. But atomic weights are usually given in atomic mass units (amu), not grams, and 1 amu = 1.66 x 10^-24 g. Therefore, we have an atomic weight of (3.35 x 10^-24 g) / (1.66 x 10^-24 g/amu) = approximately 2.02 amu. (d)

The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight.
What is atomic mass?
The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D).
The mass of each isotope is multiplied by its abundance to produce the atomic mass, which is a weighted average of all the isotopes of that element.
Any element has a variety of isotopes, thus to take into consideration the fact that each isotope has a different mass, a weighted average mass is used.
A weighted average takes into account the potential that an element's average mass, as calculated from a random sample, will most likely coincide with the average mass of its more common isotopes.
The weighted average masswill therefore be closest to that of the more prevalent isotopes.

Answer: Potassium and chlorine would form an ionic bond due to their large difference in electronegativity values (3.0 for chlorine and 0.8 for potassium). In ionic bonding, one atom completely transfers electrons to another atom to form ions with opposite charges that are attracted to each other. Since potassium loses one electron to become a positive ion (K+) and chlorine gains one electron to become a negative ion (Cl-), the resulting compound will be KCl (potassium chloride).
