Explanation:
Element is a pure substance which is composed of atoms of similar elements.
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air which conatins a mixture of ,
,
and
Explanation:
Force applied on the gas will be as follows.
As, F = pressure × area. Hence, calculate the forces as follows.
= pressure × area
=
= N
= pressure × area
=
= N
-
=
N
Substituting the calculated values into the above formula as follows.
= (m + M) g
N =
N =
m = 472.76 kg
Thus, we can conclude that the mass is 472.76 kg.
