The masses of the 2 most
common isotopes of Cl are 35 and 37. Therefore we can formulate 3 possible
masses of Cl2:
<span>
35 + 35 = 70
35 + 37 = 72
37 + 37 = 74
<span>However, Cl 35 is the most common isotope of chlorine of the
two therefore it is the most probable that two Cl 35 atoms will combine, so 70
is the most common among all.

The answer to this question would be: too low
Molar mass would be determined by the number of mol and the mass of the object. Mass wouldn't be influenced by the temperature, but number of mol is. Using ideal gas formula of PV=nRT you can conlude that the amount of mol(n) is inversely related to the temperature (T).
If the temperature is higher than it supposed to be, then the amount of mol would be lower than it supposed to be.
Answer:
6.45 joules
Explanation:
energy=10×(55-50)×0.129
=1.29×5
=6.45 J
