you breathe in 7.2 l of pure oxygen at 299 k and 100 kpa to fill your lungs. how many moles of
oxygen did you take in? (use the ideal gas law and 8.31 l *pa/mol k for the gas constant).
4.0 moles
1.2 moles
0.29 moles
2.42 moles

You will take in 2.42 moles

It makes sense because you breath 7.2 L and to make that even D would be your answer

You need to divided twenty four by a dozen them by the temperature it is getting cook by

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
