A sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.
Let us recall that the average kinetic energy of molecules depends on the molar mass of the substance as well as the temperature of the substance. We have that;
average kinetic energy=
R = gas constant
NA =Number of molecules
M = Temperature in Kelvin
We can see that the average kinetic energy depends on temperature therefore, a sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.

I’m not sure what this says could you translate it to English please?
Answer:- The weight of the arrow is 0.75 ounces.
Solution:- It is a unit conversion problem where we are asked to convert grains to ounces. We could easily do this conversion using two steps conversion, grains to pounds and pounds to ounces.
We know that, 1 pound = 7000 grains
1 pound = 16 ounces
Let's make the set up to convert 330 grains to ounces as:
= 0.75 ounces
So, the weight of 330 grains of arrow in ounces is 0.75.
