The volume of a gas at 30◦c and 0.13 atm is 61 ml. what volume will the same gas sample occupy at standard conditions?

 n= PV/RT 
n= 0.44x0.025/0.082x297.5 
n=0.000450913 

22.4L/1 mole = y L/ 0.000450913 
y=0.0101043 L 

y = 10.1 mL

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
