A gas tank contains helium, hydrogen, and oxygen gas. If the partial pressure of both helium and hydrogen is 200 torr each, and the partial pressure of oxygen is 430 torr, what is the total pressure of the gas tank?

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

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

Are there any options that could alot..

It must be measured in k.hope my answer is to you : )
