Answer:
74.10g/mol
Explanation:
The mass of one mole of Ca(OH)₂ is the molar mass of the compound.
To solve this problem, we add the atomic masses of the species in the compound;
Atomic mass of Ca = 40.078g/mol
O = 15.9994g/mol
H = 1.0079g/mol
So;
Molar mass = 40.078 + 2(15.9994 +1.0079 ) = 74.10g/mol
Answer:
At a given temperature, a system of particles can be considered as point masses (m) each moving at a certain translational velocity (v). The motion of these particles can be defined in terms of their average translational kinetic energy which is responsible for the heat transfer during molecular collisions and therefore the temperature of the system.
The kinetic temperature T is given in terms of the average translational kinetic energy as:
T = 2/3k(Kinetic energy)
T = 2/3k(1/2*m*v²)
where K = Boltzmann constant
Ans: C) Average translational kinetic energy
