A sample containing six moles of gold (I) phosphate Au₃PO₄, how many moles of oxygen atoms would be in that sample?

The sun's corona is about 6000 degree hot.

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

What are the options? i can you if you give them.

B. a graduated substance
