Answer:
0.77 M
Explanation:
Molarity is the concentration of a solution per liter
C= concentration
n= number of moles
V= volume of solution
The formula we will use is C= n/V
C= n/V
C= (1.93 mol NaCl)/(2.5 L of solution)
C= 0.772 mol/L
Since this concentration is given in moles per liters of a solution, this concentration is also the molarity.
C= 0.772 mol/L
*Include two significant digits in final answer*
M= 0.77 M
Answer:
Particle arrangement of solids: close tightly packing.
Particle arrangement of liquids: close together with no regulations and more vibration movements than in solids.
Movement of particle in gases is freely and very fast, independent from other particles.
Forces between particles in liquids are attractive forces, but not as strong as in solid state, because they have greater energy of movement and vibration then the particle in solid state.
There are no forces between particles in gaseous state, except if they are close enough, then they repel each other.
We can't compress particle in solid and liquid state, but we could in gaseous state.
Shape and volume of group of particle in gaseous state are definite.
Gas has indefinite shape and volume.
Explanation:
So you have evidence that the experiment is true or correct.
Bronze is alloy mixture of copper and tin.
I think the element that has been correctly defined by Antoine Lavoisier would be the element oxygen. He is famous for the discovery of the importance of the molecule oxygen in the process of combustion. He is is the one who characterized and named the element oxygen and hydrogen. Also, showing how these atoms combine in order to form a water molecule in the combustion process. He is considered as the father of modern chemistry as he helped in organizing nomenclature of the chemical compounds. He also is responsible for laying the foundations of the famous law of conservation of mass.
