Well, torr and Hg are different units, but they have the same conversiton with atm.
The conversion for atm to torr or mmHg is 1 atm = 760 torr = 760 mmHg.
Because you have 6.75 atm you can find both the torr and mmHg.
To use dimensional analysis just make sure that you cancel out your units as you go.
6.75 atm * (760 torr / 1 atm) = 5130 torr or 5.13 x 10 to the -3 torr with significant figures.
I hope this helped.

Answer:
139.13
Explanation:
The average atomic mass of the element Likhitium is the sum of the relative abundance of all the isotopes of Likhitium.
We obtain the relative atomic mass of Likhitium as follows;
(44.7/100 * 138) + (52.3/100 * 139) + (0.5/100 * 140) + (2.5/100 * 141)
61.7 + 73.2 + 0.7 + 3.53 = 139.13
Hence the relative abundance of Likhitium is 139.13

Answer:
Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Explanation:
Consider the following equations:


Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:

where:
Q_d is the activation energy
D_1 is the diffusivity at T_1
D_2 is the diffusivity at T_2

Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
