The atomic mass of an element is the number of times of an atom of that element is heavier than an atom of carbon taken as 12. In simpler way, atomic mass is number of protons present in nucleus of an atom, which is a characteristic of an chemical element and is determines place of the element in the periodic table. Mass number is total number of protons and neutrons. If an uncharged atom looses electron from its outermost shell, it becomes cation, which is positively charged species. Atomic number and mass number do not change if electron goes out of an atom.
Uncharged copper after loosing two electrons is converted to 
which can be represented as follows:

Answer:
<h2>2.44 L</h2>
Explanation:
The volume can be used by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the final volume
We have
We have the final answer as
<h3>2.44 L</h3>
Hope this helps you
It functions to maintain the proper pressure within the plant cells to provide structure
Answer:
The five assumption of Kinetic molecular theory are given below.
Explanation:
Kinetic molecular theory of gasses stated that,
1) Gases consist of large number of smaller particles which are distance apart from each others.
2) The gas molecules collide with each other and also with wall of container and this collision is elastic.
3) Gas molecules are in continuous random motion and posses kinetic energy.
4) The forces of attraction between gas molecules are very small and considered negligible.
5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
