9.A 2.0 L sample of helium gas is in a cylinder at 2.25 atm and 15.00C. The piston is pushed in until the sample
has a
new temperature of 37.0 C and new pressure of 3.12 atm.
What is the new volume of the gas?​

What is the question

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
