The atomic mass is measured in "atomic mass units" (amu). One mole of an element weighs the same atomic mass number, but in grams.
For example, carbon, C, has an atomic mass of 12.011 amu. One mole of carbon has a mass of 12.011 grams.
Answer:
Due to electrostatic force
Answer:
474.64mmHg
Explanation:
From the question given, we obtained the following:
V1 = 10L
P1 = 655mmHg
V2 = 13.8L
P2 =?
P1V1 = P2V2
10 x 655 = P2 x 13.8
Divide both side by the coefficient P2 i.e 13.8
P2 = (10 x 655) / 13.8
P2 = 474.64mmHg
Therefore, the new pressure will be 474.64mmHg
Answer：
It is a neutral atom and does not carry a charge
